AM4C – Vane Motors

The high starting torque efficiency of vane type motors makes them especially applicable in load hoist winch drives, swing drives and propulsion drives. This high starting torque efficiency allows the motor to start under high load without pressure overshoots, jerks and high instantaneous horsepower loads. Vane motors begin life with high volumetric efficiency and maintain that efficiency throughout their operating life. When operating at very low speeds on applications such as swing and load hoist drives, the vane motor exhibits very low torque ripple. The AM4C and AM4D vane, rotor and cam ring are pressure balanced to increase life and efficiency over full speed range. Rotating groups may be easily replaced to renew the motor or change displacement to suit altered requirements for speed or torque.
