under load without damage when protected by a relief valve.
High Efficiency A unique dual pressure plate design results in low internal leakage and overall operating efficiencies up to 90%.
Efficiency varies with motor size, pressure, speed, and fluid viscosity and temperature.
Mounting Flexibility The motor’s cover can be assembled in four positions with respect to the body.
Changing port positions is accomplished by simply rotating the cover, and the cartridge which is pinned to the cover, in 90 increments,
thus providing the optimum mounting for connecting piping.
Easy to Service The drive cartridge is accessible by removing the motor’s cover
and can normally be replaced in ten minutes without removing the motor from the machine.
The torque capability of motors within the same model series can be changed by changing the cartridge or cam ring.
Low-wear Design 25M - 50M motors are hydraulically balanced to reduce wear and heat-producing friction.
All internal inlet chambers are equally and diametrically opposed.
As a result, pressure induced radial loads are balanced. S
haft bearings only have to carry external loads so wear is greatly reduced.
Proven Reliability For more than two decades,
the reliability of these high performance motors has been field proven on a variety of machinery applications
Indirect Drive Capability Rugged two-bearing construction permits motors to be used in direct or indirect drive installations.
Indirect drive applications require approval by Vickers Engineering Department.
General Information These high speed, high pressure motors offer a choice of 12 torque ratings
from 4,7 to 33,9 Nm/6,9 bar (42 to 300 lb. in./100 psi); speeds from 400 to 3600 r/min continuous and 4000 r/min intermittent;
pressures to 155 bar (2250 psi) continuous and 172 bar (2500 psi) intermittent; reversible shaft rotation; flange or foot mounting.
Rotation Shaft rotation can be reversed simply by reversing the direction of flow through the motor ports.
General Information These motors offer a combination of low cost, pressures to 138 bar (2000 psi),
speeds to 2800 r/min, torques of 2.0, 2.8 or 4.0 Nm/6.9 bar (18, 25 or 35 lb. in./100 psi),
flange or foot mounting, and choice of port locations.
Rotation M2U motors operate in one direction only, and rotation must be specified when ordering.
Shaft rotation of M2-200 motors can be reversed simply by reversing the direction of flow through the motor ports.
Low Speed Capability Minimum speed can vary between 50 and 100 r/min , depending upon motor size and characteristics of the driven load.
Characteristics An economical, efficient and compact means of applying variable speed,
rotary hydraulic power, these motors have variable horsepower (constant torque) characteristics. They can be stalled
When properly protected by valves, the motor may be used for rapid cycle reversing or stalled without damage.
Low Speed Operation Minimum speed is normally 100 r/min. Lower speeds are obtainable,
depending upon torque requirements and the nature of the load.
Replaceable Cartridge Rotary motion is developed within the drive cartridge which consists principally of a cam ring,
rotor, ten vanes, and two pressure plates. the cartridge is bolted together so parts can be serviced separately or as an assembly.
Replaceable cartridges permit motor overhauls in just 10 minutes.
A cartridge can be replaced without removing the unit from the machine, and usually without disconnecting hydraulic lines.
Series Operation 25M - 50M motors are suited to series applications.
Inlet and outlet ports can be pressurized simultaneously without affecting service life or operating smoothness.
Indirect Drive Capability Double-row bearings are available for increased radial load capacity.
Indirect drive applications require approval by Vickers Engineering Department
Low-wear Design Two internal inlet chambers are diametrically opposed as are two outlet chambers.
This construction eliminates bearing loads resulting from pressure, a major cause of wear in designs without this feature.
Installation Flexibility The motor’s cover can be assembled in different positions with respect to the body.
To change the relative location of the ports,
it is necessary only to remove four cover bolts and rotate the cover to the desired position.
This allows optimum positioning to suit connecting piping.
High Efficiency Optimum running clearances and hydraulic balance assure sustained high efficiency over the life of the motor.
Smooth Operation Inertia of rotating parts is low ... parts are symmetrical,
providing dynamic balance and freedom from vibration.
