Product Description
Direct drive rotary motors, also referred to as torque motors, are engineered to power loads directly without the need for transmission components such as gears or belts. These motors harness strong permanent magnets to generate substantial torque. ZRT offers a selection of DDRs and can also develop tailored motors to fulfill individual needs. All ZRT direct drive rotary motors are equipped with optical encoders, guaranteeing precision for a variety of challenging tasks. By enhancing encoder resolution through interpolation, ZRT rotary motors can effectively address your precision requirements.
