firstly, the exciting magnetic field provided by the electrified conversion of the symmetrical windings in each winding on the stator 2 utilizes the action of the magnetic field on current stress and the principle that the magnetic flux is always closed along the path with minimum magnetic resistance, the exciting magnetic field passes through the magnetic flux formed by the gap between the stator 2 and the rotor 3, so that the first layer of air magnetic barrier 44 and the second layer of air magnetic barrier 45 formed by the two groups of symmetrical ferrite groups 4 close to the exciting magnetic field on the rotor 3 generate larger magnetic resistance torsion force until the path with minimum magnetic resistance is closed, the next group of symmetrical winding operation is changed, the rotor 3 always rotates in the cavity of the stator 2, the first rotor pressing plate group 5 and the second rotor pressing plate group 6 synchronously rotate together with the rotor 3, the first rotor pressing plate group 5 rotates to drive the transmission part on the machine head 8 to carry out mechanical kinetic energy motion operation, the rotation of each first fan blade 53 and each second fan blade 62 acts on heat generated by each winding on the stator 2, external cold air enters from the air cover 9, and then the heat is taken away from each heat dissipation hole 73 on the transition flange body 71.
The first air magnetic barrier 44 formed by the two first ferrites 41 on the ferrite set 4 and the second air magnetic barrier 45 formed between the two second ferrites 42 and the lower ferrite 43 can enlarge the magnetic resistance torsion angle of the rotor 3 in the maximum range and increase the rotation speed of the rotor 3.
The other two first ferrites 41, two second ferrites 42 and the lower layer ferrite 43 are obliquely designed, so that the tangential angle of resistance of magnetic resistance is increased, the torsion force of the rotor 3 is enhanced, and the mechanical kinetic energy transmitted to the machine head 8 is enhanced.
