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
