Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing:
[0013] An electric vehicle built-in permanent magnet steel wheel hub drive motor consisting of a front end cover 2, a rear end cover 8, a hub type casing 3, a rotor, a stator 6, a stator bracket 7, and a shaft 1 is characterized in that the rotor of the hub drive motor is an inner Permanent magnet rotor embedded with permanent magnet steel;
[0014] The permanent magnet rotor embedded with permanent magnet steel is composed of rectangular permanent magnet steel 4, rotor core 5, and hub-type casing 3. The rotor core 5 is evenly distributed with a plurality of rectangular slots running through the thickness of the rotor core 5. Two adjacent rectangular grooves form a positive "eight" shape or an inverted "eight" shape, the outer ends of the two rectangular grooves forming a positive "eight" shape are not connected, and the inner ends of the two rectangular grooves forming an ...
