MAGNETIC FLUX SWITCHING TYPE PERMANENT MAGNET MOTOR

摘要

A magnetic flux switching type permanent magnet motor, comprising a motor stator (110) and a motor rotor (120). The motor stator (110) comprises twelve stator tooth poles (111), a permanent magnet (130) being inserted into each stator tooth pole (111), and the magnetism of one side of one stator tooth pole (111) being the same as that of one side of the adjacent stator tooth pole (111). The motor rotor (120) comprises a plurality of rotor poles (121); and the motor stator (110) and the motor rotor (120) satisfy particular conditions. The magnetic flux switching type permanent magnet motor can simplify the motor design, and reduce the cogging torque and the torque ripple of the motor.
