HMR-02 Motor

Self-Regulating Motors for Open and Closed Circuits, Displacements from 55 to 210 cc.

These regulating motors are suitable for open and closed loop operation. They are high-pressure regulated and shift to minimum displacement Vmin at system pressures below the regulation begin point. When the defined high-pressure regulation set point is reached, the motor smoothly increases displacement to match the torque required by the system. Motor types. HMR with Vmax overrides control. The additional Vmax control enables fixed displacement motor operation independent of the control pressure.

Typical equipment options:

• Open loop circuit. Secondary (crossline relief) valves or counterbalance (brake) valves
• Closed loop circuit. Electric signal selection for a pressure regulator

Self-regulating motors for open and closed circuit steady with:

• Low-speed behavior
• High starting torque
• Large conversion range
• PTO through-drive motor
• Compact design
• High power density
• High reliability
• Long service life
• Dynamic response
