Hydraulic Vane Motor

CHARACTERISTICS

■ HIGH STARTING TORQUE EFFICIENCY
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.

■ HIGH VOLUMETRIC EFFICIENCY
Vane motors begin life with high volumetric efficiency and maintain that efficiency throughout their operating life.

■ LOW TORQUE RIPPLE AT LOW SPEED
When operating at very low speeds on applications such as swing and load hoist drives, the vane motor exhibits very low torque ripple.

■ BALANCED DESIGN
Vane, rotor and cam ring are pressure balanced to increase life and efficiency over full speed range.

■ INTERCHANGEABLE ROTATING GROUPS
Rotating groups may be easily replaced to renew the motor or change displacement to suit altered requirements for speed or torque.

■ REVERSIBLE ROTATION
The motors may be stopped or reversed repeatedly and rapidly driving or braking the connected shaft load at controlled torque levels.

■ WIDE SPEED RANGE
Starting to maximum RPM, with full torque capability during acceleration

■ PORTS AND MOUNTING
Conform fully to SAE J744c (ISO-3019-1) standards to simplify refitting and installation.

■ FIRE RESISTANT FLUIDS
Are easily used in the standard M3B and M4* versions of these motors. These include phosphate or organic ester fluids and blends, water-glycol solutions and water-oil invert emulsions.

■ M4* SERIES MOTORS
The M4* have been designed especially for severe duty applications which require high pressure up to 230 bar, high speed up to 4000 RPM and low fluid lubricity (HF-1, HF-2A, HF-3, HF-4, HF-5).
