Abstract
The invention provides a brushless electromagnetic and built-in permanent magnet series-parallel generator for electric automobile range extenders, 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, and a stator. Tile-shaped permanent magnet steel pieces are installed in circular arc slots of T-shaped salient poles of a rotor core. An electric excitation winding is wound on the T-shaped salient poles. The generated magnetic field directly faces the air gap, and there is less magnetic flux leakage. 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 magnetic field is strong, and the power density is high. 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.
