The CMG PPA & PPC series motors are designed and manufactured to be robust and reliable with minimal maintenance. The following items should be taken into consideration to ensure a trouble free installation and reliable running throughout the motor’s life.
InspectionCMG motors are delivered through safe and reliable transport in appropriate packing as to remain in as manufactured condition during transit. On receipt of the motor, thoroughly inspect the unit for any transit damage, if need be in the presence of an insurance surveyor. Any equipment damage or shortfall should be immediately advised to the nearest CMG office. Check the following:
• Ratingplatedetailsandenclosureareasordered,
• Shaftturnsfreely(inabsenceofshaftlocking clamp),
• Condensationdrainholesareinthecorrect position for the motor mounting application (They should be located at the lowest point of the motor when it is in its operating position.),
• IfthewindingisIR(InsulationResistance) tested to earth, ensure that the thermal protectors are not inadvertently damaged. (The thermistor leads should be shorted together whilst IR testing takes place).
StorageWhen the motor is not for immediate use store as follows:• Cleananddrylocation,• Freefromvibration(vibrationcan
damage bearings),• Shaftlockingclamps,wheresupplied,
are fitted securely,
• Removeshaft-lockingclampsandturnrotor by one full rotation at least once afortnightandreplaceshaft-lockingclamps,
• Anti-condensationheaters,wherefitted,should be energised if the environment is likely to be damp.
InstallationThe following items should be considered on installation to ensure reliable operation of the motor:
Surroundings• Ensurethatthemotorisproperly
protected against ingress of oil, water or dust especially if construction work is in progress around the motor,
• Ensureairintakeisnotobstructed.Referto dimension BL in the catalogue,
• Wheninstallinghazardouslocationmotors,makesurethatthezoneandgas group or dust and temperature classification on motor nameplate are complied with.
Mounting• Bedplatesorsliderailsshouldbe
firmly fixed to a solid, level foundation to ensure the motor remains rigid and vibration free,
• Shimsorpackers(ifrequired)mustbeofadequatesizeandplacedadjacenttoand between base fixings,
• Protectivetransportcoatingsonshaftsand/or flanges must be removed prior to connection to the driven load,
• Alightcoatingofgreasetoshaftsand/or flanges will inhibit corrosion during service and assist removal of pulleys or couplings.

• Noendthrustshouldbeappliedwithoutexpress approval,
• Whensliderailsareusedinconjunctionwithpulleydrives,theadjustingscrewends should be positioned between the motor and load at drive shaft end and the other diagonally opposite. This helps speedy and accurate belt aligning, tensioning and replacement.
The correct alignment of the motor pulley with the load pulley is imperative. Both these pulley’s must have matched centre distances between grooves and alignment must be carried out using a suitable metal straight edge or other recommended tools to ensure parallel offset or angular displacement of the pulley’s with respect to each other is inside permissible limits as recommended by the transmission supplier. Correct alignment will result in a uniform distribution of belt tension across the width of the pulley (and the motor shaft) and ensure design life of both the belts and bearings is achieved. Note: The pulley should always be mounted firmly against the shaft shoulder and should be a firm fit onto the shaft. Impact force must not be used.
Pulleys and couplings• Couplingsorpulleysshouldbe
independently balanced with a half key as the motor rotor is balanced with a half key during manufacture,
• Infittingcouplingsorpulleystothemotor shaft care must be taken to ensure the roller/ball bearings are not damaged. Both shaft and coupling bore should be cleaned and lubricated. If the fit is still too tight the pulley or coupling shouldbepre-heatedinairoroiltoenable easy assembly,
• Shockmethodsmustnotbeusedinfitting or removing pulleys and couplings. Proper wheel or pulley removers should be used to prevent shaft and bearing damage. Tapped holes are provided in shaft extensions to assist in the fitment of couplings and/or pulleys.
Pulley and belts• Ifthemotoristobecoupledtotheload
using pulleys and belts it is important to ensure that the belt tension does not exceed the safe working radial load of the motor. Excessive radial load will lead to reduced bearing life with the potential of breaking the motor shaft. Because of this, care must be taken to ensure the correct selection of pulley sizeandtype(toothed,veeorflat)andthis is best done in consultation with the transmission supplier.
• Thebeltmanufacturer’srecommendations for installation, alignment and tensioning must be strictly adhered to when fitting belt drives.
Alignment• Greatcaremustbetakeninaligningthe
complete machine, since misalignment can cause rapid deterioration of bearings and lead to other mechanical failures due to the stress produced,
• Afterfinaltighteningoffoundationbolts,machine alignment should be rechecked as bed plates could move and/or distort during machine mounting,

As a general rule the mid point of the applied force should be at the mid point of the shaft and it is good engineering practice to mount the motor pulley with hub and locking screw at the shaft end.
Direct coupledWhere direct coupling of the motor is required, proper alignment must be achieved to prevent bearing damage to both motor and load.
For parallel offset, use a straight edge orother recommended tools, as shown below.
Excessive angular displacement must also be prevented. The recommended method to achieve correct angular alignment is shown below.
Axial LoadsWhere motors with standard bearings are required to be mounted in either vertical shaft up or vertical shaft down orientation, there are limits on the axial forces that must not be exceeded. This also applies to horizontal mounted motors with certainloads that produce axial thrust.
Axial loads exceeding those listed in the catalogue will reduce bearing life and may lead to internal motor damage. Where higher than recommended axial loads are necessary different bearing types will be required. (Refer to CMG).
CoolingThere are various cooling formats for electric motors with IC411 (totally enclosed fan cooled) as the most common type that is used on our PPA & PPC motors. This type of cooling of motor is achieved by a fan mounted at the non drive end, inside a fan cowl which has an air inlet grille at the rear. Air is drawn in through the grille and the fan distributes the airflow along the fins of the motor body. The fan is designed for either direction of rotation (unless otherwise indicated on the fan cowl).
With TEFC motors it is important that thecooling fins remain clear of debris to allow the airflow to be fully effective in maintaining motor winding temperature within the design limits.
It is equally important to ensure the installation provides good unrestricted access to normal ambient air at the fan entry point at all times and that inlet grill is clear of contaminants. Refer to dimension BL in the PPA product catalogue.

MaintenanceA reliable, trouble free operation of a motor needs regular maintenance. Exact maintenance needs vary based on the site conditions. To obtain reliable service from the motor, the following maintenance schedule may be used as a guide. An authorised service agent must carry out maintenance ofhazardouslocationmotors.
A. Ensure air intake space is unobstructed.B. On a weekly basis use an air hose to ensure all
air ways are clear and free of dust.C. Once every month, check motor for
condensation. Replace drain plugs before starting if they are blocked or found missing.
D. Do not wash the motor down unless it is IP66 rated.
E.Onaquarterlybasis-(i) Check the motor terminals for tightness and
proper contact.(ii) Ifterminallug/sarediscoloured,re-terminate

Ensure that these figures compare well with the original records in the logbook.
(vii)Check and ensure that the cooling fan is operational.
Sealed bearings The required replacement interval for sealed bearings is generally determined by the grease life which is dependant on operating temperature, operating speed, the limiting speed of the bearing and the type of grease. Under normal operating conditions the following relationship applies:
TNn
Nnt )012.0025.0(6.254.6log −−−=
Where:t = Average grease life (hours) n = Speed (RPM) N = Bearing limiting speed with grease lubrication
(RPM)T=Operatingtemperature(°C)
Forfurtherinformation,pleasecontactyournearestCMGoffice for advice.
Open (regreasable) bearingsIt should be noted that for motors fitted with Ball and Roller bearings, the lubrication intervals for both bearings should be based on the roller bearing data.
The re-lubrication intervals recommendedare calculated on the basis of normal working conditions.
Replenishment of grease media should be by means of a hand held grease gun whilst motor is running with relief plate removed. Air operated grease guns should not be used.
Loadability Curve for VVVF Drive
NOTE:1. Applied load on the motor shall be inside the
limits specified by this loadability curve.2. PPA Ex nA motors are suitable for operation with
VACON brand variable frequency drives or drives of equivalent characteristics.
3. These motors supplied by frequency converters must be fitted with thermal protection devices such as thermistors in winding so as to cut the supply to the motor in the event of an over temperature. Recommended protection by using NXOPTA3 card with thermistor protection feature in the variable speed drive.
