PERMANENT MAGNET MOTOR
Provided is a permanent magnet motor, comprising a rotor component (1) and a stator component (2). The rotor component (1) comprises alternating poles (4) and permanent magnet poles (3) alternately arranged in a circumferential direction. The stator component (2) comprises stator teeth portions (5)...

Abstract | Provided is a permanent magnet motor, comprising a rotor component (1) and a stator component (2). The rotor component (1) comprises alternating poles (4) and permanent magnet poles (3) alternately arranged in a circumferential direction. The stator component (2) comprises stator teeth portions (5) arranged and spaced apart in a circumferential direction on an inner circumferential side of the stator component. A first air gap (6) is formed between an inner circumferential side of the stator teeth portion (5) and an outer circumferential side of the permanent magnet pole (3). A second air gap (7) is formed between the inner circumferential side of the stator teeth portion (5) and an outer circumferential side of the alternating pole (4). An average thickness of the first air gap (6) is δ1, and an average thickness of the second air gap (7) is δ2, wherein 0.4 ≤ δ2 / δ1 ≤ 0.9. The permanent magnet motor of the present application can reduce asymmetry of flux density amplitudes of air gaps corresponding to the permanent magnet pole and the alternating pole, and thereby reducing torque ripples. |
