Control Circuit of Forward Reverse Starter

Working of Forward  – Reverse starter control circuit

Forward direction

  • Press ON Push button ( F ON )
  • The forward contactor coil gets supply through phase R – OFF push button – R2 – forward contactor coil – ON push button F – phase Y.
  • The forward contactor coil energized and three phase induction motor runs in the forward direction. 
  • As soon as forward contactor energized, its auxiliary contact F1 becomes normally closed ( NC from NO ) whereas F2 becomes normally open ( NO from NC ). 
  • Now the forward contactor gets supply through phase R – OFF push button – R2 – Forward contactor coil – F1 – phase Y.

Reverse direction

  • Press ON push button ( R ON ).
  • The reverse contactor coil gets supply through phase R – OFF push button – F2 – reverse contactor coil – R ON push button – phase Y.
  • The reverse contactor coil energized and three phase induction motor runs in the reverse direction.
  • As soon as reverse contactor energized, its auxiliary contact R1 becomes normally closed ( NC from NO ) and R2 becomes normally open ( NO form NO ).
  • Now the reverse contactor gets supply through phase R – OFF push button – F2 – Reverse contactor coil – R1 – phase Y. 
  • The auxiliary contact R2 becomes NO from NC therefore the motor does not run in the forward direction.
