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.
