Abstract:
1. A cross-interlocked multi-set switch type DC brushless electric machine system having an auxiliary excitation winding set, which relates to a multi-set switched DC brushless electric machine having its rotary part installed with an auxiliary excitation winding set, for being connected in series with a magnetic field winding set of another electric machine through the auxiliary excitation winding set installed on the rotary part of the electric machine, such that the excitation can be variable through altering the current of the magnetic field winding set of the another electric machine, comprising: a first drive control device ( a first magnetic field structure ( the first magnetic field winding set ( a first electric machine angular position sensor ( the first rotary part ( the first auxiliary excitation winding set: constituted by conductive wires wound on the magnetic pole of the first rotary part ( the first electric conductive annular brush device ( a second drive control device ( a second magnetic field structure ( the second magnetic field winding set ( a second electric machine angular position sensor ( the second rotary part ( the second auxiliary excitation winding set ( the second electric conductive annular brush device (
