Using their knowledge of power and control technologies, Mitsubishi Heavy Industries has developed a new direct drive servo motor (DD Motor) for use in injection molding applications. Coupled directly to the injection ball screws without using synchronizing belts or pulleys, the DD Motor provides superior injection performance.

 

 

Features and Benefits of the DD Motor

  • High power, low speed/high torque motors directly coupled to the injection ball screws
  • Injection response is improved due to the lower inertial moment
  • Energy saving because power transmission losses are reduced
  • Easier to maintain - No need to adjust belt tension
  • Noise is reduced
  • Synchronized electronic control of four motors without belts or pulleys
  • Airborne particulates are reduced
