Hybrid excitation flux reversal motor

Abstract

The invention discloses a hybrid excitation flux reversal motor. The motor comprises a stator, a rotor and a rotary axle. The rotor comprises a rotor yoke and a rotor pole. The stator comprises a stator yoke and a plurality of stator poles connected with the stator yoke. Each stator pole comprises a stator pole body, a stator pole shoe and a stator pole arc surface. A stator power winding wire casing is arranged between each two adjacent stator poles. A stator power winding is arranged in the stator power winding wire casing. Two stator permanent magnets with opposite polarity are glued on each stator pole arc surface symmetrically. A stator excitation winding winds the corresponding stator pole shoe relative to each stator permanent magnet, and the two stator excitation windings on each stator pole are connected in series mutually. The hybrid excitation flux reversal motor has the advantages of adjustable excitation magnetic field and a simple structure.

Description

technical field [0001] The invention relates to a magnetic flux reversing motor, in particular to a hybrid excitation magnetic flux reversing motor. Background technique [0002] As the energy crisis continues to intensify, it has become a worldwide consensus to use permanent magnet excitation instead of electric excitation to save energy consumption. At the same time, since my country is the country with the most abundant rare earth resources in the world, it is of great theoretical significance and practical value to develop, research and promote the application of rare earth permanent magnet motors with new structures. However, due to the shortcomings of the permanent magnet motor itself that the air gap magnetic field cannot be adjusted, it has become a bottleneck that limits its application and promotion. [0003] At present, for the hybrid excitation motor based on the rotor permanent magnet motor, the proposed motor structure is very complicated. Regardless of the m...
