Abstract

The invention provides a salient electromagnetic pole and permanent-magnet invisible magnetic pole mixed excitation power generation device with a vacuum pump, and belongs to technical field of automobile motor electric appliances. The device consists of the vacuum pump, a front end cover, a rear end cover, a mixed excitation rotor, and a stator. A first rectangular permanent magnet steel is embedded into a first rectangular groove on a T-shaped salient pole. A second rectangular permanent magnet steel is embedded into a second rectangular groove on the T-shaped salient pole. An excitation winding is disposed on the T-shaped salient pole in a winding manner. A magnetic field in a power generator gap is provided by the permanent magnet steels and the excitation winding, and the generated magnetic field directly faces the gap, so the leakage flux is small. A 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. The device can supply electric energy to the power utilization equipment of an automobile, and also can supply vacuum servo energy to a braking system.
