Direct Drive and Hollow Shaft Motors

Electric motors are preferable to other motor types in many motor transmission applications. Harmonic Drive offers direct drive and hollow shaft motors that can add substantial value to your manufacturing processes. Direct drive motors can drive a load without a speed reduction mechanism, making them ideal for applications requiring rapid acceleration. They perform well in manufacturing processes characterized by frequent starts and stops due to their low torque requirement for acceleration. Benefits include efficiency from lower friction loads and partial load accommodation, reliability due to simple design and minimal backlash, less maintenance with fewer components, and exceptional precision. A hollow shaft motor features an innovative design with a hole in the center, allowing components to pass through the rotational axis. This motor type performs well in various robotics, automation, and precision manufacturing applications. Highlights include being lightweight, space-saving due to compact design, and enhanced torque generation for higher energy demand applications. The KDU series offers advanced direct drive motors with exceptional positional accuracy (10 arc-sec) and repeatability (±0.5 arc-sec), featuring a large hollow shaft design. The HMA series provides hollow shaft motors in five frame sizes, enabling cables, lasers, and shafts to pass through the axis of rotation.
