CHARACTERISTICS - M5B* SERIES

12 vanes and a patented cartridge design allow a very low noise level, whatever thespeed.

The M5B series has been designed especially for severe duty applications wich requirehigh pressure , high speed and low fluid lubricity.Max. pressure (intermittent) M5B* 012 to 036: 320 bar

M5B* 045 : 280 bar

Max. speed (intermittent, low loaded cond.) M5B* 012 - 018 : 6000 RPMM5B* 028 - 036 : 4000 RPMM5B* 045 : 3000 RPM

Up to 90 % overall at 320 bar.Vane motors begin life with a high volumetric efficiency, and maintain that efficiencythroughout their operating life.Vane pin holdout design improves the mechanical efficiency at low pressure.

The high starting torque efficiency of the vane type motors allows them to start underhigh load without pressure overshoots, jerks and high instantaneous horsepower loads.

This 12 vane type motor exhibits a very low torque ripple (typical ± 1,5%), even at lowspeeds.

The vane, rotor and cam ring are pressure balanced to increase life over the full speedrange. Double lip vanes reduce the sensitivity to fluid pollution.

Our precise manufacturing allows any component to be interchangeable.Rotating groups may be easily replaced to renew the motor or change the displacementto suit altered requirements for speed or torque.

The M5B-M5BS are bi-directional motors, externally drained.The M5BF, externally drained, is available in three types of rotation : bi-directional,clockwise, counter-clockwise.The M5BF1, internally drained, is available in two types of rotation : clockwise, andcounter-clockwise.

The uni-directional M5BF and M5BF1 are designed with an internal valve that allowssmooth dynamic braking, with a very simple hydraulic circuit and without risk ofmotor cavitation.

M5B - M5BS : Cylindrical keyed or splined shaft according to SAE J744, ISO 3019-2 orJ498b.These products are designed primarily for coaxial drives which do not impose axial orside loading on the shaft.

M5BF : A stiff taper or cylindrical keyed shaft and a high load capacity double ballbearing allow the direct mounting on shaft (fan, ...).

DESCRIPTION - M5B* SERIES

The floating side plate contains a shuttlevalve which passes a higher pressure signal

to the clamping area.The cartridge is a replaceable

assembly including the cam ring,rotor, vanes, pins and springs.

The vane is urged outward by thepin force, spring force and

centrifugal force.

Port A ramp whereunloaded vane moves

outward for CWrotation

Major arc wherefluid works to push

vane.

Port B ramp unloadedvane moves inward for

CW rotation.

Section A-AThe pin cavity is

at a steadypressure equal tothat at inlet port.

The cam ring isinterchangeable with

others of differentdisplacement. It has lub

coating on innersurface.

The side grooves andradial holes cause

undervane and overvanepressure to be equal.

The rotor is ofthrough-hardenedhigh alloy steel.

The rotation ischanged by

reversing theflow.

Minor arc wherevane works to

seal inletpressure from

outlet port.

The side feed holessupply inlet pressure to

pin cavity.

M5BF M5B - M5BS

• The motor shaft is driven by the rotor. Vanes, closely fitted into the rotor slotsmove radially to seal against the cam ring. The ring has two major and two minorradial sections joined by transitional sections called ramps. These contours and thepressures exposed to them are balanced diametrically.

• Hydraulic pins and light springs urge the vanes radially against the cam contourassuring a seal at zero speed so that the motor can develop starting torque. Thesprings and pins are assisted by centrifugal force at higher speeds. Radial groovesand holes through the vanes equalize radial hydraulic forces on the vanes at alltimes. Fluid enters and leaves the motor cartridge through opening in the sideplates at the ramps. Each motor port connects to two diametrically opposed ramps.Pressurized fluid entering at Port A torques the rotor clockwise. The rotortransports it to the ramp openings which connect to Port B from which it returns tothe low pressure side of the system. Pressure at Port B torques the rotorcounter-clockwise.

• The rotor is separated axially from the sideplate surfaces by the fluid film. Thefront sideplate is clamped against the cam ring by the pressure, maintains optimumclearance as dimensions change with temperature and pressure. A 3-way shuttlevalve in the sideplate causes clamping pressure in Port A or B, whichever is thehighest.

• Materials are chosen for long life efficiency. The vanes, rotor and cam ring aremade out of hardened high alloy steels. Cast semi-steel sideplates are chemicallyetched to have a fine crystalline surface for good lubrication at start-up.

PORTS AND HYDRAULIC FLUIDS - M5B* SERIES

This motor may be alternately pressurized on ports A and B to 320 bar max.Whichever port is at low pressure, it should not be subjected to more than 60% of thehigh pressure, eg : When 320 bar in A, B is limited to 200 bar.

This motor must have a drain line connected to the center housing drain connection ofsufficient size to prevent back pressure in excess of 3,5 bar, and returned to thereservoir below the surface of the oil as far away as possible from the suction pipe ofthe pump.

This unidirectional motor may be pressurized only on the port corresponding to itsrotation type.The outlet pressure must not be higher than 3,5 bar.

Petroleum base anti-wear R & O fluids (covered by DENISON HF-0 and HF-2specifications).Maximum catalog ratings and performance data are based on operation with thesefluids.

They are easily used in the M5B* motor. These include phosphate or organic esterfluids and blends, water-glycol solutions and water-oil invert emulsions.

The use of fluids other than petroleum base anti-wear R & O fluids requires that themaximum ratings of the motor will be reduced. In some cases, the minimumreplenishment pressure must be increased.

HF-1 : non antiwear petroleum base.HF-3 : water in oil emulsion.HF-4 : water glycols.HF-5 : synthetic fluids.Max. press. int. : 240 bar (HF-1, HF-4, HF-5) 175 bar (HF-3)Max. press. cont. : 210 bar (HF-1, HF-4, HF-5) 140 bar (HF-3)Max. speed : 1800 RPM (HF-3, HF-4, HF-5)

Max. fluid temperature (HF-0, HF-1 & HF-2) _________________________+ 100° CMin. fluid temperature (HF-0, HF-1 &HF-2) ___________________________ - 18° C

The fluid must be cleaned before and during operation to maintain a contaminationlevel of NAS 1638 class 8 (or ISO 18/14) or better. Filters with 25 micron (or better, ß10 ≥100) nominal ratings may be adequate but do not guarantee the required cleanlinesslevels.

Maximum acceptable content of water is :• 0,10 % for mineral base fluids• 0,05 % for synthetic fluids, crankcase oils, biodegradable fluids.If amount of water is higher, then it should be drained off the circuit.
