Answer Posted / kuttivenu
Single-phase or polyphase synchronous motors can't start
without being driven, or having their rotor connected in
the form of a self-starting circuit. Since the field is
rotating at synchronous speed, the motor must be
accelerated before it can pull into synchronism.
Accelerating from zero speed requires slip until
synchronism is reached. Therefore, separate starting means
must be employed.
