Product Description
Direct drive rotary motors, also referred to as torque motors, are designed to drive loads directly without the need for transmission elements such as gears or belts. These motors use strong permanent magnets to generate substantial torque. ZRT offers a variety of DDR choices and can design custom motors to fulfill unique needs. All ZRT direct drive rotary motors are equipped with optical encoders, guaranteeing accurate performance in challenging applications with improved resolution using interpolation.
