Brushed DC Motors (Wound Field)

Wound field DC (WFDC) motors typically have higher torque and speed capabilities than their permanent magnet counterparts. Nidec Drive Systems offers a range of robust, proven WFDC motors with a variety of available enclosures, mounting types and other features. Available WFDC motor types include:

Series wound

  • Armature and field are wound in a series
  • Provides high starting torque
  • Ideal for applications where a simple contactor or very simple speed control is used

Separately excited (sepex)

  • Armature and field are wound separately
  • Provides greater control over rotor speed
  • Best for traction applications, requires a more advanced controller

Compound wound

  • Utilizes a combination of series and parallel wound field coils
  • Provides optimized performance within a certain load range
  • Used most often in pumping applications
