Precise Direct Drive Motors

High torques even with heavy loads

Direct Drive Motors

High torque. High payload. High accuracy.

The DDA direct drive motor is a rotary actuator that directly drives a rotary table with a motor without using any speed reducing mechanism such as a belt or reduction gears.

Eliminating the speed reducing mechanism explains why high speed and excellent response can be attained with such a compact frame.

The series includes models designed for high torque and high payload up to 90 or 270 kg. This makes it very easy, for example, to integrate rotary indexing tables in an automation system.
