Synchronous Motor Protection & Control

The SPM controls starting, synchronizing, and protection of collector-ring or brushless type synchronous motors.

 

Applications:

  • Collector-ring synchronous motors

 

Protection & Control

  • Field application

  • PF regulation maximizes efficiency

  • Reluctance torque synchronizing

  • Re-synchronizing

  • DC field current loss

  • DC field voltage check

  • Incomplete sequence

  • Field winding over temperature

  • Power factor (pull-out)

  • Stall/acceleration

  • Restart lockout
