Piston motor has a variable displacement (two-speed) swash plate and incorporates a brake valve and a mechanical brake needed for travelling. The TM motor with planetary gear reducer offers outstanding features. The hydraulically balanced piston motor ensures reliable changeover of the displacement by external pilot control (1.5 ~ 2 : 1 speed ratio)

The motor offers speed control and braking with minimum shock with a built-in double counterblance valve and shockless relief valve. (These valves are not necessary for a closed circuit.) The mechanical brake is a negative. The brake is automatically activated or released upon stop or start.

The case rotation type gear reducer has improved durability and reliablity because of its simple and equally loaded design in addition to high-precision machine parts.The motor uses heavy duty bearings to ensure long life. An efficient floating seals also prevent dust and water from entering the motor.
