Permanent magnet exciting motor

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
