Abstract
The invention provides an embedded permanent magnet and claw pole electromagnetic hybrid generator, and belongs to the technical field of automobile motor electric appliances. The generator consists of a front end cover, a rear end cover, a hybrid rotor, a stator, and an electronic voltage-stabilizing controller. Rectangular permanent-magnet steels are respectively embedded in a first rectangular groove and a second rectangular groove of a T-shaped salient pole of a rotor core. An exciting winding is disposed on the T-shape salient pole in a winding manner, and the generated magnetic field directly faces the gap, so the leakage flux is small. The magnetic field in a generator gap is jointly provided by the permanent-magnet steels and the exciting winding. The magnetic field intensity is high, and the power density is high. Through the adjustment of the size and direction of a power-on current of the exciting winding, the magnetic field formed by the synthesis of a permanent magnetic field and an electromagnetic field can be adjusted. An output voltage of the generator is stable, and the safety and reliability of automobile electric appliances are guaranteed.
