Abstract:
1. A switch type DC electric machine having an auxiliary excitation winding and conduction ring and brush, which provides a switched DC electric machine ( 1000 ) in which a rotary part ( 104 ) of the electric machine ( 1000 ) composed of a rotary part of a permanent magnetic electric machine or a rotary part of a reluctance electric machine of the switched DC electric machine ( 1000 ) is installed with a serial type auxiliary excitation winding set ( 105 ) and/or a parallel type auxiliary excitation winding set ( 108 ), and an electric conductive annular brush device ( 107 ) serves as an interface for transmitting electric power; a drive control device ( 103 ) is used for controlling the value and the polarity and the phase sequence of excitation current of a magnetic field winding set ( 102 ) of the electric machine ( 1000 ) and is also equipped with one or more than one of following functions: (A) controlling the value and the polarity of an excitation voltage and current of the serial type auxiliary excitation winding set ( 105 ); (B) controlling the value and the polarity of excitation voltage and current of the parallel type auxiliary excitation winding set ( 108 ); (C) controlling the value and the polarity of excitation voltage and current of both or one of the serial type auxiliary excitation winding set ( 105 ) and/or the parallel type auxiliary excitation winding set ( 108 ); wherein as a result of the control function provided by the drive control device ( wherein the drive control device (
