CMM SERIES GEROTOR MOTOR
1 / 3Pages

CMM SERIES GEROTOR MOTOR – LOW SPEED – HIGH TORQUE APPLICATIONS Use the CMM Series for light to medium duty applications such as grain augers and elevators, salt and sand spreaders, car wash and sweeper brushes, conveyors, winches, scissor lifts, and many other. To assure optimum motor life, run motor for approximately one hour at 30% of rated pressure before application of full load. The Prince CMM Series of high-torque, low speed motors incorporates the orbiting gerotor principle for dependable operation over a wide range of applications. Although dimensionally small, this motor is capable of providing considerable power over a wide speed range and is instantly reversible by simply reversing the direction of the hydraulic fluid flow. The needs of many applications requiring high starting, stall and running torque combined with slow speed are met by this motor. Feature • Fully reversible simply by reversing the direction of hydraulic fluid flow. It is not recommended to operate at a condition requiring both maximum torque and speed. Splined shafts are recommended in application operating at above 2500 in-lbs. continuous torque or under conditions of frequent reversal. CROSS REFERENCE CHARLYNN “H” Series • Alternative port positioning for versatility of installation. (see next page). DANFOSS “DH” Series • Optional shaft configurations. (see next page). • Modular construction for economical servicing and repair, also permits special adaptations. Filtration 10 micron or finer. (Per ISO cleanliness code level 17/14.
