Example Embodiment

[0017] Due to different phase numbers and different structures, the double salient pole motor with magnetization generator and electric excitation double salient pole motor with 3-phase 6 / 4 structure is similar to the double salient pole motor with magnetization generator with 3-phase 6 / 4 structure. A motor is used to illustrate a specific implementation.

[0018] The electrical excitation double salient pole motor of the present invention with a magnetization generator and an electric excitation double salient pole motor with a 3-phase 6 / 4 structure is shown in FIG. 2 . Excitation current i f It flows in from the positive terminal if+ of the excitation winding, flows out from the negative terminal if- of the excitation winding, and generates an excitation flux from left to right inside the excitation winding. If the current flows out from the positive end of the A, B, and C three-phase windings, and the negative end flows in, a load flux from left to right is generated insid...

Abstract

The invention relates to a double salient electro-magnetic motor for magnetism increasing electricity generation, which is a special electric generator. The negative terminals of all the phases of windings of the generator are connected together, and are led out through a wire; the negative terminals are used as the cathode of the generating system of the double salient electro-magnetic motor. Each phase of the windings is separately connected with the anodes of diodes; the cathodes of the diodes are connected to a point and are led out through a wire; the cathodes of the diodes are used as the anodes of the double salient electro-magnetic motor for magnetism increasing electricity generation. The anode and the cathode of the double salient electro-magnetic motor for magnetism increasing electricity generation are separately connected with the anode and the cathode of a load to supply power for the load. The invention is characterized in that the voltage regulation rate and the excitation loss are reduced by utilizing the magnetism increasing armature reaction of the load, and the invention applies the basic electromagnetic property of the double salient electro-magnetic motor, thereby improving the performance of the double salient electro-magnetic motor for magnetism increasing electricity generation.

Description

1. Technical field [0001] The magnetically-increased generator and electrically excited double salient pole motor of the present invention belongs to a special generator. 2. Technical Background [0002] The stator and rotor of the switched reluctance motor and the doubly salient pole motor are salient pole structures, and both belong to the variable reluctance motor, which has the advantages of simple structure, low price and high reliability. When the switched reluctance motor works as a generator, a position sensor is required, and an active power converter is required for excitation control and power output, which increases the cost and complexity of the system and reduces the reliability of the system. Electric excitation doubly salient motor (patent number: ZL 99114250.0) does not require rotor position sensor and power converter, and the system has high reliability. Adopting multi-pole structure and double stator structure (Chinese invention patent application number...
