List several methods for starting synchronous motors. Check all that apply. Start the motor as an induction motor relying on the amortisseur conductors to produce torque. Use a prime mover to bring the motor up to synchronous speed before connecting the source. Synchronous motors can start without being driven, or having their rotor connected in the form of a self-starting circuit. Use an electronic system to convert 60-Hz power into three-phase ac of variable frequency. Start with a frequency of one hertz or less and then gradually increase the frequency.
