Abstract

The invention provides a permanent-magnetic invisible magnetic pole and brushless electromagnetic series-parallel generator, and belongs to the technical field of automobile motors and appliances. The generator comprises a front end cover, a rear end cover, a series-parallel rotor, a stator, and an electronic voltage regulation controller. Rectangular permanent magnet steel pieces are installed in tangential rectangular slots of T-shaped salient poles of a rotor core. An electric excitation winding is wound on the T-shaped salient poles. The magnetic field in the air gap of the generator is provided jointly by the permanent magnet steel pieces and the electric excitation winding. The generated magnetic field directly faces the air gap, and there is less magnetic flux leakage. By adjusting the magnitude and direction of the current flowing through the electric excitation winding, the magnetic field which is formed by compositing a permanent magnetic field and an electromagnetic field can be adjusted. The output voltage of the generator is stable. The safety and reliability of the electrical equipment of electric automobiles are ensured.
