Problems solved by technology

[0006] The purpose of the present invention is to overcome the disadvantage that the ordinary asynchronous motor cannot realize pole-changing and speed-changing if the centralized winding is used, and to provide a magnetic pole spaced winding combined stator that adopts the centralized winding and can realize pole-changing and speed-changing asynchronous motors

Abstract

The present invention relates to a motor stator, in particular, a magnetic pole spaced winding combined stator. The magnetic pole spaced winding combined stator includes a stator component A and a stator component B; the stator magnetic poles of which the serial numbers are odd numbers, of the stator component A and the stator component B and the stator magnetic poles of which the serial numbers are even numbers, of the stator component A and the stator component B, are arranged alternately; in the winding machining process of a concentrated winding, a large machining operation space is provided between two adjacent stator magnetic poles, and therefore, the slot opening width of stator core wire slots can be reduced under a condition that the winding machining of the concentrated winding is not affected, or closed slots can be adopted as the stator core wire slots, and therefore, a cogging torque can be lowered, a brushless direct-current motor or permanent magnetic synchronous motor can use integer-slot windings, the selection range of the number of slots and the number of poles in the design of the brushless direct-current motor or the permanent magnet synchronous motor can be extended, and the performance of the motor can be improved. The combined stator can realize pole variation and speed variation when applied to an asynchronous motor, so that the asynchronous motor can be facilitated to decrease an additional torque generated by a tooth harmonic magnetic field, and therefore, the efficiency of the motor can be improved.

Description

technical field [0001] The present invention is a magnetic pole spaced winding combined stator, which relates to a motor stator, in particular to a concentrated winding coil sequentially wound on the iron core pole body and the magnetic pole insert of two stator iron cores, And the magnetic pole inserts of the two stator cores are alternately inserted into the motor stator of the tongue and groove between two adjacent iron core pole bodies of the opposite stator core. Background technique [0002] The motor stator winding coil is divided into two structural types: distributed winding and concentrated winding. Most asynchronous motors use distributed windings, while brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM) use centralized windings. The processing technology of distributed winding is complicated, and the processing technology of centralized winding is simple. The interphase insulation strength of centralized winding is higher than that of dis...
