MT series hydraulic motors have working displacements from 160 to 725 cm? /rev. and deliver 40 kW of power. Some of the main characteristics of this type motors is that they have constant working displacement and achieve high torque at low speed. The main part of the MT motor is the gear set comprised of; rotor with 8 teeth, stator with 9 teeth and rollers. Apart of increasing the motor performance and efficiency, the rollers reduce the friction and therefore increase the life of the motor.
