General characteristics

The F classification of the winding insulation is based on its capability to run atmaximum temperature.

This temperature 155°C [ 311°F ] represents the maximum running temperature forthe winding. In other words, if the motor ran 40 hrs a week in a clean and dryenvironment, its life expectancy would be 10 to 20 years before the insulationdeteriorates due to heat to the point that it can no longer withstand the appliedvoltage.

Definitions

Maximum turning speed allowed. [ nmax ]

The maximum speed nmax depends on the mechanical design [roller bearings life,short-circuit ring of the squirrel cage] and electrical design [voltage limitingcharacteristics]. Never exceed this speed value.

Maximum permanent speed. [ n1 ]

It is the maximum speed allowed permanently [ regardless of the speed duty cycle ].

S1 duty cycle [ continuous ].

Operation with constant load long enough to stabilizate the temperature of themotor.

T : Duration of the cycle

P : Power of the load

Pp : Lost electrical power

S6 duty cycle [intermittent operation].

Uninterrupted periodic service with intermittent load, also called [continuous cyclewith intermittent load]. It consist of a series of identical cycles that have a constantload time and another one without load. There in no resting [stopped] intervals. If noother value is indicated, the duty cycle with load will be referred to a time period of10 minutes. Thus:

S6 - 40% indicates:t c = 4 minutes with loadt v = 6 minutes without load.

Motor limits. For induction motors, the speed and power values are limited for thermal andmechanical reasons. The maximum current is only limited by the thermalcharacteristics of the motor windings.

• Thermal limit:

Heat loss is stored in the motor and dissipated by coolings systems. The motortemperature depends, among other things, on the duty cycle with load. This criticalmotor temperature must never be exceeded.The characteristics for continuous cycle S1 and intermittent cycle S6 [40%] definethe outputs allowed for an ambient temperature of up to 40°C. For this case, thewinding temperature increase is about 100° C.

• Mechanical limit:

The mechanical speed limit must never be exceeded. Exceeding this value maydamage the roller bearings, the short-circuit ring of the rotor,...

Operating modes

Next, the motor operating modes are described showing the different zones in the di-agram below [ power-torque / speed ]. The motor behavior characteristics are differentin each of them.

For spindle motors it is crucial to have an ample constant power zone. Three operatingzones are established in order to analyze this characteristics.

The following graph shows each zone and the motor operating mode in each if them.

Operating zones:

• Zone 1:

This zone is established from the resting state [zero speed (0 rpm)] to the ratedoperation point [rated or base speed].

The torque supplied by the motor is the same as the rated or nominal [ MN ] andit is constant in the whole zone. Its value is obtained by multiplying the powergenerated by the motor [which is directly proportional to the current running throughits rotor until the rated operation point is reached] and its corresponding turningspeed.

The power generated by the motor is directly proportional to the speed up to therated operation point where it reaches the rated or nominal power [ PN ].

• Zone 2:

This zone is defined as the constant power zone and covers from the nominal op-erating point to where the motor reaches its maximum available voltage.

The torque decreases proportional a the speed increases.

The power remains constant.

• Zone 3:

This zone begins when the voltage at the motor terminals has reached the maxi-mum voltage that the drive can provide.

The torque decreases with the square of the speed.

The power decreases as the speed increases.

12


SPM motor manual

Influence of the supply voltage

The supply voltage of the bus sets the electrical limitation on how the motor will run.

In zone 2, the power is kept constant. However, in zone 3 it decreases as the speedincreases. Since on most spindle applications, it works in zone 2 at constant power,this zone should be as wide as possible.

The transition from zone 2 to zone 3 takes place because there is no enoughvoltage to keep compensating the voltage drop at the stator impedance.Therefore, in general, the more voltage the drive can provide, the wider zone 2[constant power] will be.

When the operating mode of a motor is in zone 3 and it does nor provide thenecessary power, a larger motor will have to be used or increase the voltageprovided to the drive.

The following diagram shows these limits:

Technical data and characteristics

Power graphs - turning speed: associated drive

The AC motors of the SPM series for main spindle drives must be ventilated at all timeswhile running regardless of the duty cycle.

These power graphs are for duty cycles S1 and S6 - 40% - [duty cycle of 10 minutes].

Note that the S6 appearing on the graphs shown later on will always refer to the S6 - 40 % -.

To determine the modular or compact spindle drive associated with each motor, referto the graphs overlapping those of the motors.

For more information, see the section “characteristics table” of chapter 6 in this manual.

The tables next to the graphs offer the technical data for each model.

Precautions when installing the motor

This section describes the environmental precautions to bear in mind wheninstalling the motor.

The motor must be installed under the following conditions:

• There must be a gap between the armature of the motor and the structureof the machine never smaller than 5 mm [ 0.1968 pulgadas ] in order toavoid electromagnetic interference and transmission of vibration.

• Install the motor in the ambient conditions indicated in table 1. of generalcharacteristics in chapter 1. Bear in mind it must be installed in a clean anddry place away from corrosive environments and explosive gasses orliquids. Protected with a cover if it will be exposed to oil splashes.

• It must be easily accessible for inspection and maintenance.

• Ensure free air flow around the motor and allow the best air input andoutput possible.

• The motor must be fitted onto flat, solid and sturdy surface. If the motorsuffers excessive vibrations, it is often due to the weakness of the basesupporting it.

• When foot mounted, the supports are located on the base of the motor itselfand its dimensions and supports are standard. The motor must be mountedonto a perfectly flat surface in order to avoid deforming and breaking theprotections which could cause contact between the rotor and the stator. Ifnecessary, step up the motor support until perfectly flat and uniform motormounting is achieved. Any element used to step it up must be made of theproper material and not smaller, in dimensions, than the motor foot itself.

• Secure the motor with the right size bolts, nuts and self-locking washers.Make sure that the tools used to secure the motor do not interfere with itsoperation or damage it.

The flange and the shaft of the motor have an anticorrosive layer of paint or grease. Theflange, the shaft and the key must be cleaned before installing the motori

When installing it in difficult areas due to dust, water, too much humidity, vapor, smokes,oil, solvents,... a motor meeting a higher sealing standard may be ordered.i

Ball bearings: Useful life and precautions

The special bearings are suitable for speeds up to 9000 they are lubricated withspecial greases resistant to high rotation and temperature conditions.

The maximum theoretical life of the bearings is calculated in about 20000 hours ofcontinuous operation at 1500 rpm approx. For higher average rotation speeds, thelife of the bearings varies as follows:

30 - 50 % de nmax. - about 16000 hours.50 - 60 % de nmax. - about. 12000 hours. 60 - 70 % de nmax. - about. 8000 hours. The data and the operating hours are calculated for normal operating conditions,without vibrations and with temperatures within the limits imposed by the bearingmanufactures.

The speed nmax is to intented as the maximum limit of rotation and not ascontinuous operating speed, which is limited to about 70% of nmax.

Notes:

On the non drive side, a rigid radial ball bearing is always installed :

The meaning of the terms used in this equation is:

Fr = Radial load [ N ]

Nn = Nominal speed [ rpm ]

Pn = Nominal power [ kW ]

D = Diameter of pulley [ mm ]

Pp = Weight of pulley [ N ]

k =

1 - 1.5 for cog belts

2 - 2.5 for V belts

3 - 4 for flat belts

Fr 19 5 6×10,Pn k⋅D Nn⋅--------------- Pp±⋅=

31


SPM motor manual

Balancing

The rotor is dynamically balanced with the key inserted in the keyway. It is an Sdegree balancing and, upon request, an SR degree can be obtained. It is importantthat the pulley half-joint or rack be dynamically balanced [ without the key ] beforeinserting them in the transmission shaft. Any vibration while the motor is runningindicates an unbalanced gear box and must be corrected.

• Make sure to break the motor in during the first start-up.• Increase the motor speed gradually from 0% to 70% of nmax in about 20 minutes.• Do not run the motor too long at its maximum speed.

• Watch the temperature values and for any strange noises.• During the first minutes of operation, a loud noise might be heard because the ball

bearings are not uniformly lubricated. By the end of the break-in period, the noiseshould reach its normal volume.

• The sealing rings to protect the ball bearing may be removed if you feel that they arenot necessary because the environment is very clean or other external protections arebeing used to reduce friction and temperature levels.

Do not hit the ball bearings because it will shorten their life.

32


SPM motor manual

Mounting the gear boxes

Upon request, the motor may carry a special flange for mounting gear boxes.

The joints, pulleys, pinions,... must always be adjusted very accurately and with theright tools.

Before manipulating the gear box, remove the anti-rust paint from the motor shaft byusing alcohol or the proper solvent [the solvent must not get into the bearings]. Donot use sandpaper or any other abrasive element to remove the paint.

Lubricate the end of the shaft and the keyway before inserting the transmissión and assemble it by following the manufacturer‘s instructions.

Radial and axial loads

A misalignment between the motor shaft and the machine axis increases vibrationat the shaft and shortens the life of the ball bearings and couplings. Likewise,exceeding certain radial load values may cause a similar effect on the ball bearings.

Con el fin de evitar estos problemas deberán seguirse las siguientesconsideraciones:

• Use flexible couplings when the coupling is direct.

• Avoid radial and axial loads onto the motor shaft, making sure that they donot exceed the values indicated in the table 1.

Note that when installing gears, any blow to the shaft decreases its useful lifespan, that ofthe bearings and may damage the encoder. Therefore, do not hit it for any reason.

33


SPM motor manual

Note:

For combined axial and radial loads, decrease the value of the allowed radial force to 70%.

Note that when installing transmission pulleys or gearboxes, any blow to the shaft reducesits useful life, of beraings, and may damage the encoder. Therefore, do not hit it for anyreason.

• Make sure that the maximum radial load values at the end of the shaft do not exceedthe permitted values shown in the table 1.

• Exceeding these radial load values increases the vibration of the shaft and shortens thelife of the ball bearings and couplings.

35


SPM motor manual

Coupling considerations

The circular motion of the motor can be transmitted to the machine through directcoupling or by using pulleys or gear boxes.

Direct coupling. Considerations

• Always couple the motor to the machine when the motor shaft and that ofthe machine are aligned. Insert a coupling for adjustment if necessary.

• If the motor shaft is not aligned with the center line of the machine axis,skewing the motor in an attempt to align them may damage the externalball bearings and shorten its life.

• If while the motor is running it vibrates or turns abnormally, it may be dueto poor alignment and may cause the motor shaft to break.

• Due to the difficulty of achieving an exact and reliable coupling, this type ofcoupling is only recommended when no transmission pulleys or othercoupling devices are possible.

Belt coupling. Considerations

• Make sure that the motor is mounted in parallel with the machine axis andthat the center lines of the pulleys and of that of the shafts form a rightangle. This avoids the axial pressure on the supports.

• The tension of the belts must be enough to prevent slippage when themotor is working at full load. It must never exceed the maximum loadindicated by the belt manufacturer in their technical catalog.

• Too much tension on the belt may amage the bearing and even break theshaft.

fig.3 Direct coupling between the motor shaft and the machine axis

36


SPM motor manual

• The radial load on the motor shaft must not exceed the values indicated inthe corresponding table. See the section on radial and axial loads.

• If the belt angle is not the right one, it may cause vibration or slippage.

• When applying an excessive load on the motor shaft, the ball bearings maybe seriously affected and their life drastically shortened.

• Make sure that the contact angle between the belt and the pulley its layingon is φ = 140° or greater. Otherwise, it will generate some slippage. Seethe section: Belt installation.

• To know the belt peripheral speed, its transmitted power and diameterratio, etc. refer to the data supplied by the belt manufacturer.

• Always use balanced pulleys.

Gear coupling. Considerations

• Make sure that the motor shaft is mounted parallel to the machine axis andthat the centers of the gears are in parallel alignement engaging perfectly.

• The gear teeth will deteriorate if they do not engage properly.

• Refer to the data supplied by the gear manufacturer.

Mounting a pulley or a gear to the motor shaft

• When installing a pulley or a gear to the motor shaft, take into account themotor balancing.

fig.4 Belt installation

37


SPM motor manual

• The rotor is dynamically balanced with the key inserted in the keyway. It isimportant that the pulley half-joint or rack be dynamically balanced [withoutthe key] before inserting them in the transmission shaft.

• When the motor turns at high speed, any mechanical disturbance maycause vibration. Any vibration while the motor is running indicates anunbalanced gear box and must be corrected.

Joints, pulleys, pinions, etc. must be mounted exactly and using the proper tools. Neveruse a hammer to do this because it could damage the bearing and the accessories.

fig.5 Transmission gear installation. Do not use a hammer

• Before mounting the transmission gear, remove the anticorrosion paint of the motorshaft and keyway using alcohol or the right solvent.

• Lubricate the end of the shaft and the keyway before inserting the gear and mount it asinstructed by the manufacturer.

SPM motor manual

Ventilation

General considerations

All SPM series spindle AC motors have an electrical cooling fan that generates aconstant air flow regardless of the motor turning direction. This assures propermotor cooling in all duty cycles.The motors can run at their rated current or peak current at low speeds withoutlosing their specifications.

Fan connection

The fan must be connected to single-phase 220 Vac at [ 50/60 Hz]. On mostmotors, it is carried out through a terminal box.

Only SPM 90 motors use a connector that is provided with the motor.

Maximum cable section, 2.5 mm2.

fig.1 on the next page shows the location of the fan on the motor.

The electric fan must be turned on before powering the motor and must never bestopped while the motor is on.

• Make sure that the air going in is dry, clean and cool.• For motors installed inside the structure of another machine and/or protected by panels

or other type of covers, it is absolutely essential that the air comes in from theatmosphere through the ventilation openings.

• The cool air intake and the hot air outlet must be as far away from each other aspossible in order to avoid mixing them.

MAINTENANCE


SPM motor manual

General considerations

Checks prior to start-up

• Turn the shaft by hand verifying that it does so freely.• Verify that there are no strange objects inside the motor fan protection or

in the cooling channels that may have entered while being assembled orwas in storage. If so, remove them.

• Verify that the nuts and bolts of the motor transmission elements areproperly fastened.

• Verify that the connections to the terminal box of the motor and the driveare properly done and that the characteristics plate indicates the it is OK toconnect it to the power supply.

• Verify that the fan works properly and in the indicated direction.• Check the other accessories and make sure that it is properly mounted and

connected.

Checks after start-up

• Watch for possible vibration in the motor and transmission gears.• Check the voltage at the power supply and the current consumption

against the values indicated by the characteristics plate.• Verify that the maximum consumption of the drive under all load and speed

conditions are within the values indicated by the characteristics plate.

Maintenance periods

First inspection:

First inspection in normal cases and after about 500 hours of operation, at any ratewithin a year from start-up date. Check that the plate data are followed and thereare no vibrations, noises, high temperatures or structural damages to the motor andaccesories.

Re-lubing of bearings:

Fagor recomends the lube oil from KLUBER [ ISOFLEX LDS 18 SPECIAL A ] .

Periodic inspections

The maintenance and inspection periods, in general, depend on the type ofbearings, dimensions, average speed and temperature conditions. This period, inour case, will be between 1000 and 8000 hours. In any case, they should be donebefore three years.

63


SPM motor manual

Use the following formula to calculate the amount of lubricant for the bearingaccording to its outside diameter and its height:

where:

Gp = amount of lubricant [ gr ]

D = Outside diameter of the bearing [mm] B = Bearing height [mm]

Nevertheless, it is recommended to refer to the bearing manufacturer’s catalog.

Replacement of the bearings:

The bearings must be replaced before 20,000 hours of operation. To replace them,follow the instructions described in the next section.

Note that the type of bearing is shown in the section: Bearing characteristics inchapter 3.

Always use the same lubricant for the bearings or one with equivalent specifications.

Do not add too much lubricant so as not to generate high temperatures and contaminatethe motor.i

SPM motor manual

Selecting the motor and the spindle drive

This whole motor selection considers 5 basic aspects that condition the operatingcharacteristics of the motor - machine assembly.

• Characteristics of the motor itself• Load demands• Service conditions• Ambient conditions• Power supply

As far as load demands are concerned, machine-tool spindles must keep their rpmconstant. This speed is controlled by the drive which will determine the necessarytorque to be applied on to the load according to its characteristics as well as theadjusted accelerations and decelerations.

A procedure to determine the power required from the motor is:

• According to the request load, establish the value of the required ratedpower [continuous, instant and periodic ].

• Increase the value of the required power taking into account the efficiencyof power transmission and load dispersion.

Drive selection

Once the motor has been selected, refer to the characteristics table of this sectionthat shows the references of the modular SPD spindle drives and compact SCDdrives associated to the selected motor.
