Wherein, it is edge magnetic bridge width that the magnetic, which hinders edge to the rotor edge distance, and the edge magnetic bridge width 5 is set
For s, 0.7 millimeter≤s≤1.3 millimeter.
Wherein, the magnetic barrier selects air as un-conducted magnetic material, and the magnetic barrier is the U-type groove opened up.
The magnetic barrier of each magnetic barrier is of same size.
In the present embodiment, the rotor selects axial laminated rotor.The axial direction laminated rotor includes several rotors
Piece 1, the rotor sheet 1 select silicon steel sheet.
In the present embodiment, the magnetic barrier width B0 of reasonable magnetic barrier 2, the reasonable side of edge magnetic bridge 5 are designed on d axis and q axis

Degree is different.
The source that synchronous magnetic resistance motor generates torque is that dq axle inductance is poor, and torque equation is as follows:
T=3/2*P/2* (Ld-Lq) * id*iq,
Wherein, P is number of pole-pairs.
To improve output torque, the difference in inductance of d axis q axis is the bigger the better, and in order to increase difference in inductance, magnetic is arranged in q axis direction
