Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings:
[0013] The composite permanent magnet invisible magnetic pole and brushless electromagnetic hybrid excitation drive motor is composed of a front end cover 9, a rear end cover 1, a casing 3, a hybrid excitation rotor, and a stator 4. It is characterized in that: the hybrid excitation rotor is composed of a carbon brushless slip ring structure. It is composed of claw pole type electric excitation rotor and composite permanent magnet invisible magnetic pole rotor;
[0014] The composite permanent magnet invisible pole rotor is composed of a shaft 2, a rectangular permanent magnet steel 8, a tile permanent magnet steel 5, a rotor iron core 6, and a pear-shaped slot magnetic isolation air gap 7. The rotor iron core 6 is evenly distributed with an even number of penetrating rotors. The radial rectangular groove with the thickness of the iron core 6, the outer end of the radi...
