Abstract

The invention provides a motor, a compressor and a refrigerating device, wherein the motor includes: a stator core, provided with a rotor hole that runs through the stator core, wherein the stator core includes a plurality of first stator teeth and second stator teeth arranged in alternate manner and equal in quantity; the maximum tooth width of the second stator teeth is less than the minimum tooth width of the first stator teeth; the width of the tooth roots of the second stator teeth is greater than that of the tooth crests of the second stator teeth; a stator winding wound on the first stator teeth; a rotor arranged in the rotor hole. The structure of the second stator teeth is configured into a structure wherein the width of the tooth roots is greater than that of the tooth crests, sothat gaps between the tooth crests of the second stator teeth and the first stator teeth increase in size, a stator winding of more coils can be wound, motor efficiency is improved, high power density is achieved for the motor, and manufacture cost of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor, a compressor and refrigeration equipment. Background technique [0002] At present, the permanent magnet synchronous motor adopts concentrated winding group. Each coil of the concentrated winding motor is wound on a stator tooth, which shortens the end length of the winding and the axial length of the motor, reduces the amount of copper used, and reduces the total copper of the motor. consumption, thereby improving the efficiency of the motor. The slots and poles commonly used in concentrated rolls are 6 slots and 4 poles, 9 slots and 6 poles, and 12 slots and 8 poles (such as figure 1 As shown), the winding coefficient of the motor is 0.866, while the winding coefficient of the distribution coil with 18 slots and 6 poles is 1, but the top of the distribution coil with 18 slots and 6 poles is high, the amount of copper used is large, and the utilization rate of copper wi...
