To reverse the direction of rotation of acapacitor start motor while it is running we should___________?
Correct answer: A. disconnect motor from the supply till it stops then reconnect it to supply with reversed connection of main or auxiliary winding
- A. disconnect motor from the supply till it stops then reconnect it to supply with reversed connection of main or auxiliary winding
- B. disconnect motor from supply and immediately reconnect it to supply with reversed connections of the main winding
- C. reverse the direction of connection of the auxiliary winding and after motor comes to rest then connect auxiliary winding to the supply
- D. reverse the direction of connections of the auxiliary winding and immediately connect it to supply
Explanation
Reversing a capacitor-start motor while it is rotating can cause severe current and mechanical stress, so it must first be disconnected and allowed to stop. The main or auxiliary winding connection can then be reversed before restarting.
