Parker Low-Speed–High-Torque Motors
Build Program

Low-Speed-High-Torque (LSHT) motors are a cost-effective and reliable part of a hydraulic system that can transmit a large amount of power from a small drive envelope. They can operate smoothly at speeds as low as 0.1 rpm and have a maximum shaft speed of up to 1,000 rpm. LSHT motors are often used in industrial settings where slow, controlled movement with significant force is needed. These motors are direct drive, eliminating the need for mechanical transmission elements like gearboxes, timing belts, and worm gear drives. You can easily identify LSHT motors in the field by their donut shape.  

The Parker LSHT motors’ high quality and robust design makes these motors a great choice for numerous applications such as grapple rotates, conveyor belts, augers, and wheel motors.
