What is the "DD"(Direct Drive Motor) ?

Pick Up

A method or mechanism that directly transmits the rotational force of an electric motor to a drive object without using mechanical mechanisms such as reduction gears, belts, or pulleys.

Advantages of Direct Drive Motors

  • High efficiency (minimizes losses due to friction in the reduction mechanism)
  • Low noise (simple mechanism reduces the number of parts that cause contact and vibration, thus eliminating mechanical noise)
  • High precision (backlash-less)
  • Highly reliable and maintenance-free
  • Improved speed ripple (vibration during operation), Vibration improvement by direct drive

  • Space saving
  • Multi-angle positioning (360-degree positioning is possible for index tables with fixed divisions)
