The invention relates to a motor stator, a motor and a rotor type compressor. The motor stator comprises a stator core of which an inner circumferential surface is provided with teeth and tooth grooves alternately arranged along the circumferential direction, and a stator winding which is provided with enameled wires, wherein the enameled wires penetrate through the tooth grooves and are wound onthe teeth, at least one heat dissipation enhancing groove is further formed on an inner circumferential face of the stator core, and the heat dissipation enhancing grooves are formed at the tops of the teeth. The motor stator is advantaged in that the motor stator is low in cost and good in heat dissipation effect, so the motor has good heat dissipation performance without depending on a cooling duct, that a rotor type compressor applying the motor is low in cost and good in stability is guaranteed, and the motor stator is suitable for being applied to economical and practical refrigeration electric appliances. 本发明涉及一
