Product Description
Direct drive rotary motors, also known as torque motors, are specifically engineered to power loads directly without the use of any transmission components like gears or belts. These motors utilize powerful permanent magnets to produce significant torque. A wide range of DDR options and custom motors are available to meet specific requirements. All direct drive rotary motors come with optical encoders, ensuring precise performance in even the most demanding applications with enhanced resolution through interpolation.
