The advantages that gathering, be efficient, power density is big.But existing axial flux permanent magnet motor structure simultaneously not perfect, the knot of generally use
Configuration formula is durface mounted permanent magnet body form, and generated air gap flux density is relatively low, thus the performance of motor and not up to one compared with
Good degree.In addition, the generally use oOrdinary silicon steel sheet material in axial flux permanent magnet motor, fails to play this motor
Structural advantage.
Existing axial flux permanent magnet motor can be divided into the structure of no yoke portion iron core and have the structure of yoke portion iron core, both
Structure respectively has disadvantage, is unfavorable for the raising of motor performance.In the axial permanent magnetic motor of the structure of no yoke portion iron core, due to no yoke
Portion relatively low there are the stator structure intensity of the motor while manufacture difficulty is higher.In the axial permanent magnetic electricity for having yoke portion core structure
In machine, it since yoke portion takes part in magnetic conduction, therefore can only be made of isotropic silicon steel sheet, reduce the efficiency of motor.
Document CN201310088701 be a kind of conventional surface paste the unilateral axial flux permanent magnet motor of rotor, the motor due to
Using surface sticking structure, therefore its air gap flux density is relatively low, causes motor output torque relatively low, while the mechanical strength of the structure
Relatively low, when motor is in high-speed cruising, the centrifugal force suffered by rotor permanent magnet is larger, easily causes motor damage.While by
