HMC Series Motor

Dual Displacement, High Torque, Low Speed, Radial Piston Motor.

The range of the HMC motors extends from the HMC010 of 202 cm³ (12.3 in³) to the HMC325 of 5330 cm³ (325 in³) displacement. These motors are also available in a continuously variable version using either hydro-mechanical or electro-hydraulic control methods.

The HMC series dual displacement models have two pre-set displacements which can be chosen from a wide range to suit specific application requirements. The displacements are hydraulically selected by a directional control valve which can be remote from, or mounted directly on, the motor. Displacements can be changed when the motor is running.

The HMC high torque, low speed, dual displacement motor is designed for rigorous industrial, marine, and mobile applications where dual or continuous displacement is required.
