Abstract

The invention provides a motor, a compressor and a fan. The motor comprises a rotor core, a rotor slot-pitch and a stator core, wherein the rotor slot-pitch is arranged on the rotor core in a penetrating manner, and is inclined relative to an axial direction; the stator core is arranged on one side of the rotor core; and the stator core comprises stator teeth facing the rotor core, air gaps are formed between the stator teeth and the rotor core, and at least part of the air gaps are not equal. According to the invention, the inclined rotor slot-pitch is arranged on the rotor core, and the air gaps which are not completely equal or completely unequal are formed between the stator teeth and the rotor core, so the requirements of reducing the fluctuation quantity of a low-speed harmonic torque and improving the output performance of the motor are met, and the starting addition of the motor and rated performance can be matched with each other.

Description

technical field [0001] The present invention relates to the technical field of motor equipment, in particular, to a motor, a compressor and a fan. Background technique [0002] At present, with the continuous deepening of DC technology in electrical appliances, automobiles and other technical fields, in application scenarios such as fans in electrical appliances and compressors in automobiles, the requirements for the operating efficiency of motors are getting higher and higher. [0003] However, the existing motor structure design is still faced with a large starting additional torque of the motor in the actual application process, and it is difficult to match the starting and rated performance. SUMMARY OF THE INVENTION [0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies. [0005] To this end, a first aspect of the present invention is to provide a motor. [0006] A second aspect of the pr...
