Chapter 4 Hydraulic Actuators 4.1.3 Low-speed motors Low-speed motors are usually radial piston motors.They possess high pressure and large delivery to meet the needs of low speed rotation and large torque.Because of their large size and large moment of inertia,they are not suitable for the applications which require rapid response and frequent direction changing Low-speed motors may be further classified based on how they function:(1)single-acting motors which provide a push in one direction;(2)double-acting motors which provide push in both directions;(3)multiple-acting motors which provide push in many directions. 13 Homepage List Upwards Downwards Retumn ExitChapter 4 Hydraulic Actuators 13 4.1.3 Low-speed motors Low-speed motors are usually radial piston motors. They possess high pressure and large delivery to meet the needs of low speed rotation and large torque. Because of their large size and large moment of inertia, they are not suitable for the applications which require rapid response and frequent direction changing. Low-speed motors may be further classified based on how they function: (1)single-acting motors which provide a push in one direction; (2)double-acting motors which provide push in both directions; (3)multiple-acting motors which provide push in many directions
