Abstract

The invention provides a motor, a compressor and refrigeration equipment. The motor comprises a first stator punching sheet which comprises a plurality of first stator teeth, wherein each first statortooth comprises a first tooth part and a first tooth boot disposed at the first tooth part; a first magnetic conduction part is arranged on one side, deviating from the first tooth part, of the firsttooth shoe; a rotor is rotatably arranged in an inner hole of the stator; the rotor comprises a plurality of rotor petals, each rotor petal is provided with a group of magnets, the rotor petals are provided with second magnetic conduction parts along the peripheral side of the rotor, and when the straight axis of the rotor located on the rotor petals coincides with the symmetric center line of the first tooth part, the second magnetic conduction parts located on the rotor petals are located on the side, facing the rotating direction of the rotor, of the straight axis of the rotor. According to the motor provided by the invention, the radial electromagnetic force wave generated by the interaction of the armature magnetic field harmonic wave and the rotor magnetic field harmonic wave is low, and thereby the vibration noise of the key frequency band of the compressor is ameliorated, and the noise of the motor is reduced, and further efficiency of the motor is improved.
