Abstract

The invention discloses a stator assembly and a motor. The stator assembly comprises a stator core and a stator winding. The stator core has 36 stator slots. The stator winding comprises A, B, and C phases of stator windings, the common end of the A, B, and C phases of stator windings is in a star connection or triangular connection. The A, B, and C phases of stator windings comprise four sets of coil groups, and each set of coil groups comprises a large coil, a middle coil and a small coil. The large, middle and small coils of each set of coil groups of the A, B, and C phases of stator windings are uniformly embedded into the 36 stator slots according to a rule that the winding pitches of the large coils are 8, the winding pitches of the middle coils are 6, and the winding pitches of the small coils are 4, wherein the a double-winding design is employed by the A, B, and C phases of stator windings, and the elements of two different phases are placed in each one of the stator slots. According to the invention, the structure of the motor stator winding is improved, the magnetic saturation of a motor stator magnetic circuit is reduced, and the output performance of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly and a motor. Background technique [0002] The motor stator is one of the important parts in the motor, mainly composed of stator core and stator winding, which is used to generate the excitation magnetic field. At present, the stator slot of the stator core is usually designed with 24 slots, and the three-phase stator winding is used for single-layer or double-layer winding. This kind of motor has a small winding pole pitch, and the stator magnetic circuit is easy to saturate during operation, and the high-order harmonic content High, it is easy to generate heat and reduce the output performance of the motor. Contents of the invention [0003] The main purpose of the present invention is to provide a stator assembly, aiming at improving the stator magnetic field, reducing the high-order harmonic content, reducing the calorific value of the motor, and improvin...
