Hybrid vehicle driving motor stator core structure

Abstract

The invention discloses a hybrid vehicle driving motor stator core structure. The hybrid vehicle driving motor stator core structure comprises a stator yoke portion with an annular structure and a ring of stator tooth portions connected with the inner ring of the stator yoke portion, wherein gullets for filling coils therein are formed between adjacent stator tooth portions, and the inner ring of the stator yoke portion and the inner end of the ring of the stator tooth portions are of buckling connection structures. According to the invention, the stator yoke portion is of an integrally formed annular structure, such that the circularity of the outer circle of a stator is guaranteed, and interference assembling between a stator iron core and a motor housing is facilitated; the stator yoke portion and the ring of the tooth portions are of the bucking connection structures, the assembling is simple, the assembling efficiency of the stator iron core is improved, and the production cost can be effectively reduced; and when the stator yoke portion and the stator tooth portions are of split structures, the stator tooth portions can be individually replaced when being damaged, replacement of the stator yoke portion is unnecessary, materials are reduced, and at the same time, the service life of a motor is prolonged.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a hybrid electric vehicle drive motor stator core structure. Background technique [0002] In order to solve the two major social problems of environmental pollution and energy shortage, my country has begun to vigorously develop new energy vehicles to replace traditional fuel vehicles, and hybrid electric vehicles (Hybrid Electric Vehicle, HEV) are typical representatives. A hybrid electric vehicle refers to a hybrid electric vehicle equipped with two power sources (thermal power source and electric power source) at the same time. Compared with traditional fuel vehicles, hybrid vehicles have lower fuel consumption because the internal combustion engine always works in the best condition, and can recover braking energy; compared with pure electric vehicles, hybrid vehicles reduce the number of battery packs, which is easy to manage , and can guarantee a longer mileage. Therefor...

AI Technical Summary

Problems solved by technology

The assembly of this structure is more complicated, and it is difficult to ensure the outer roundness of the stator core after assembly, which is not convenient for the interference assembly of the stator core and the motor housing, which reduces the efficiency of motor assembly and increases the cost

The stator teeth are easily damaged when the motor is running. The stator teeth of this structure cannot be replaced separately, which wastes materials
