Zusammenfassung:	A starting control system for synchronous motors is provided in which the usual separately mounted discharge resistor is eliminated. A relatively high resistance coil of small size is wound on each field pole, in addition to the normal field winding, and these coils are connected together and utilized as a discharge resistor during starting of the motor.
