HMC045 Precision Engineered Motor for Reliable Performance

HMC045 two-speed motor has two preset displacements to choose from a wide range to suit specific application requirements. Control and selection is made via directional valve which can be remotely mounted or directly mounted on the motor. The displacement can be easily changed while the motor is running.

Key features

1. Onload twospeed shift: switch largedisplacement hightorque / smalldisplacement highspeed while running, controlled by hydraulic valve; optional electrohydraulic control, freewheel functionKawasaki P....

2. Hydrostatic balanced valve plate, good starting torque, stable lowspeed performance, shockload resistant.

3. Wide fluid compatibility: antiwear oil, waterglycol, HFA/HFB/HFD fluids (derate for nonmineral oil)Kawasaki P....

4. Case drain: continuous case pressure ≤3.5 bar for standard shaft seal; highpressure seal optionalKawasaki P....

Typical applications

· Marine: winches, anchor windlass, hatch cover drives

· Industry: shredders & crushers, injectionmolding screw drive, slewing drives, winches, mining equipment

Common symptoms to watch

1. Higher casedrain flow → internal wear (valveplate / pistonlink assembly).

2. Noise + vibration → oil contamination, bearing wear, cavitation.

3. Twospeed not switching → check shift pilot pressure.
