Product Description
Direct drive rotary motors (DDR) are motors that are designed to drive loads directly without the need of any transmission mechanism , such as gear or belts. These motors are also called torque motors. They use high energy permanent magnets to generate high torque . ZRT offers various types of DDRs, We also design customized direct drive motors according to spec. All ZRT direct drive rotary motors are equipped with optical encoders. With higher encoder resolution after interpolation, ZRT rotary motors can satisfy your need of precision in any type of demanding applications.
