Novel motor stator structure

Abstract

The invention relates to the field of motors, and specifically discloses a novel motor stator structure. The stator comprises two identical iron core main bodies which are spliced into a metal annularstructure in a manner of mirror symmetry. The outer side of each iron core main body is sleeved by an upper insulating frame and a lower insulating frame, which are paired. A stator winding which isformed by the winding of enamelled copper wires in the same direction in the winding ducts are disposed in the plurality of winding ducts formed by the combination of the upper insulating frame and the lower insulating frame. According to the invention, the vertical winding of a conventional motor rotor is changed into parallel welding, thereby simplifying the production technology, enabling the assembly to be more convenient, enabling the reliability to be higher, greatly improving the production efficiency, and saving the manpower resources for assembly. The stator is low in structure complexity, improves the production and installation precision of the stator assembly, improves the reliability and consistency of the motor, and is better in performances. The stator assembly is higher inspace utilization rate, is good in heat dissipation performance, and is large in winding space utilization rate.

Description

technical field [0001] The invention relates to the field of electric motors, and specifically discloses a novel motor stator structure. Background technique [0002] With the development of modern industry, electricity is gradually replacing heat as the main energy utilization method for human beings. In the application of electricity, the motor is an important part. [0003] Traditional motors use the magnetic field generated by the energization of the stator winding whose magnetic field direction is perpendicular to or slightly deflected to the rotor to drive the rotor to rotate, that is, the central axis of the winding is perpendicular to the tangent of the stator axis circle, or slightly deflected. Referring to the Chinese patent CN207304178U, it specifically discloses a stator core for a dual-rotor motor and a dual-rotor motor with it. The central axis of the core and the winding of the motor are both perpendicular to the tangential direction of the axial center circl...

AI Technical Summary

Problems solved by technology

[0004] In the production of this traditional motor, since the stator winding and iron core need to be perpendicular to the normal line of the rotor, the winding process is very complicated and cumbersome. Although the combined iron core makes the winding process relatively simple, the processing cost of the iron core is high , It takes time and effort to assemble the iron core with the wire wound, which greatly increases the cost of manpower and material resources, and the space occupied by the wire winding is large, and the power of the motor with the same volume is difficult to increase
