Abstract
The invention provides an electromagnetic and combined type permanent magnet series-parallel power generation device, and belongs to the field of automobile motor electric appliances. The device consists of a front end cover, a rear end cover, a series-parallel rotor, a stator, and an electronic voltage-stabilizing controller. Rectangular permanent magnet steels are respectively embedded into a first rectangular and a second rectangular groove on a T-shaped salient pole. An excitation winding is disposed on the T-shaped salient pole in a winding manner. A generated magnetic field directly faces the gap, so the leakage flux is small. A magnetic field in a power generator gap is jointly provided by the permanent magnet steels and the excitation winding. The intensity of the magnetic field is large, and the power density is high. The magnetic field formed by the synthesis of a permanent magnetic field and an electromagnetic field can be adjusted through adjusting the size and direction of a power-on current of the excitation winding. The output voltage of the power generator is stable, thereby guaranteeing the safety and reliability of the automobile motor electric appliances.
