The outer ring 24 is connected to magnetic isolating inner retaining ring 14 via a locking bolt 7, which is convenient for the rotor core 9 to rotate around the main shaft 4.

[0056] A plurality of tread inner supporting sheets 13 are welded on the outer wall of the rotor core 9. Outer ends of tread inner supporting sheets 13 are welded on the inner wall of the magnetic isolating ring 25. All tilt angles of the tread inner supporting sheets relative to the outer wall of the rotor core are the same, and the tilt angle between the tread inner supporting sheet and the outer wall of the rotor core is preferably 15-30 degrees which is not only capable of playing a good role in supporting but also able to cushion by the deformation of the tread inner supporting sheets in the event of impact.

The outer side of the rotor core 9 is assembled with the wear-resistant tire 10 and the inner wall of the wear-resistant tire is support by the magnetic isolating ring 25 and a plurality of the tread inner supporting sheets 13.

[0057] The main shaft 4 is fixed at its inner end with a terminal A 19 and a terminal B 21. The terminal A 19 is connected to the winding end wire of the stator winding 3 through a wire embedded in the main shaft 4, the terminal B 21 is connected to the conductive ring 18 fixed on the main shaft 4 through the wire embedded in the main shaft 4. A collecting ring 17 is fixed on and electrically connected to the outer wall of the conductive ring 17, in which the outer wall of the collecting ring 17 is abutted against a brush 16. The brush 16 is connected to a winding end wire of the filed winding 11 through the wire embedded in the magnetic isolating inner retaining ring 14.

[0059] The operating principle of the present disclosure is as follows:

[0060] While a vehicle installed the magnetic controlled wheels based on electromagnetic propulsion system works, the fixed shaft 20 welded on the inner end of the main shaft 4 is fixedly connected to the frame of the vehicle, and then respectively, the terminal A19 is electrically connected to stator winding 3, the terminal B21 is electrically connected to the field winding 11, and the terminal C is electrically connected to the commutation pole winding 29. When a three-phase alternating current with a phase separation of 120 is applied to the field winding, a rotating magnetic field will be generated. Since the rotating magnetic field rotates and the stator winding 3 is stationary, the rotating magnetic field of the stator will be cut by the stator winding 3 to generate an induced electromotive force. According to the right-hand rule, it is determined that both ends of the stator winding 3 are short-circuited by the short-circuiting ring, under the action of the induced electromotive force, the stator winding 3 will generate an induced current which is basically consistent with the direction of the induced electromotive force. The current-carrying conductor of the stator core 2 is subjected to an electromagnetic force in the rotor magnetic field, the direction of which is determined by the left-hand rule. And the electromagnetic force generates electromagnetic torque relative to the main shaft 4. Since the main shaft 4 is welded to the fixed shaft 20, the rotor core 9 is driven reversely to rotate along the opposite direction of the rotating magnetic field; thereby the rotor core 9 drives a plurality of tread inner supporting sheets 13, magnetic isolating ring 25 and wear-resistance tire 13, which realizes the movement of the magnetron wheel body 1. The bearing part 6 between the rotor core 9 and the main shaft 4 improves the rotation stability of t the rotor core 9, a plurality of tread inner supporting sheets 13, the magnetic isolating ring 25, and the wear-resistant tire 10, and changes the current direction in the stator winding 3, the field winding 11, and the commutation pole winding 29, which facilitates driving the magnetron wheel body 1 to reversely rotate and realizes the commutation of the magnetron wheel body 1.
