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 400to 3600 r/min continuous and 4000r/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. When properly protected by valves, the motor may be used for rapid cycle reversing or stalled without damage.
Low-Speed Capability
The minimum speed is normally 100 r/min. Lower speeds are obtainable, depending upon torque requirements and the nature of the load.
Low-Speed Operation
The 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 port scan 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.
