Abstract:
1. A cross-interlocked switch type DC electric machine having auxiliary excitation winding and conduction ring and brush, which relates to a multi-set switched DC electric machine having conduction ring and brush having its rotary part of electric machine being installed with an auxiliary excitation winding set, for being connected in series with a magnetic field winding set of electric machine of another electric machine through the auxiliary excitation winding set installed on the rotary part of electric machine, such that the excitation can be variable through altering the current of the magnetic field winding set of electric machine of the another electric machine, and it mainly consists of: first drive control device ( first magnetic field structure of electric machine ( first magnetic field winding set of electric machine ( first electric machine angular position sensor ( first rotary part of electric machine ( first serial type auxiliary excitation winding set ( first electric conduction ring and brush device ( second drive control device ( second magnetic field structure of electric machine ( second magnetic field winding set of electric machine ( second electric machine angular position sensor ( second rotary part of electric machine ( second serial type auxiliary excitation winding set ( second electric conduction ring and brush device (
