第一

本发明属于电机制造技术领域，公开了一种永磁激磁电机，包括定子结构、以及内置于定子结构中的转子结构，该定子结构包括定子轭、设置于定子轭上的多个第一定子齿与多个第二定子齿、以及设置于相邻第一定子齿与第二定子齿之间的电枢绕组，相邻第一定子齿与第二定子齿之间具有定子槽，各第一定子齿上设有第一定子分裂齿与第二定子分裂齿，各第二定子分裂齿上设有第一定子永磁体。这样，第一定子分裂齿和第二定子齿可实现对磁场调制的作用，此外，在第二定子分裂齿上设有第一定子永磁体，避免了永磁体设置于整个第一定子齿上，减少了永磁体的用量，提高了单位磁体体积的输出转矩。

The invention belongs to the technical field of motor manufacturing, and discloses a permanent magnet exciting motor. The permanent magnet exciting motor comprises a stator structure and a rotor structure arranged in the stator structure; the stator structure comprises a stator yoke, a plurality of first and second stator teeth arranged on the stator yoke, and armature windings arranged between the adjacent first and second stator teeth; stator grooves are formed between the adjacent first and second stator teeth; a first split stator tooth and a second split stator tooth are arranged on eachfirst stator tooth; and a first stator permanent magnet is arranged on each second split stator tooth. In this way, the first split stator teeth and the second stator teeth can achieve the effect of magnetic field modulation; and in addition, the first stator permanent magnets are arranged on the second split stator teeth, so that the permanent magnets are prevented from being arranged on the whole first stator teeth, the usage amount of the permanent magnets is reduced, and the output torque of unit magnet volume is increased.
