Abstract

The present invention comprises: a housing having a refrigerant suction port through which a refrigerant is sucked, and a refrigerant discharge port for discharging the sucked refrigerant that has been compressed; a stator disposed in a ring-shape inside the housing; and a rotor that is disposed at the inner side of the stator and rotates. The stator comprises shoes having one side surfaces facing the rotor, teeth that are integrally extended from the other side surfaces of the shoes in a radial direction and on which coils are wound, and head portions having inner circumferential surfaces integrally formed on the outside of the teeth and outer circumferential surfaces facing the inner surface of the housing. The angle between the other side surface of each of the shoes and the side surface of each of the teeth can be formed into an obtuse angle in order to reduce the rapidly forming magnetic flux density near the magnetic pole conversion region of the rotor. Therefore, forming the stator into an optimal shape for reducing the rapidly forming magnetic flux density near the magnetic pole conversion region of the rotor reduces cogging torque and torque ripple, and further reduces noise and vibration thereof. Additionally, setting the optimal condition for the interval between the slots, which is the main variable in the shape of an electromotive force, not only enhances the efficiency of the motor, but also achieves smoother operation thereof and reduces the noise and vibration of same.
