The integrated rotor high torque WD motor is for light duty use in industrial and mobile applications. While its’ footprint is small, its spool valve design offers high-efficiency over a wide range of speeds and torque levels. Internal pressure on the seals is relieved through an integrated check valve and built-in check valves improve seal life. The WD also allows the use of a case drain. A variety of low-profile ports contribute to the compact design and light weight.
