Novel single-phase asynchronous AC motor stator structure

Abstract

The invention relates to a novel single-phase asynchronous AC motor stator structure and relates to the field of single-phase asynchronous AC motor. The stator structure in the prior art has disadvantages in manufacturing process such as too many steps, complex operation and low utilization rate of silicon steel sheet. The invention comprises a stator core, an insulating bushing arranged on outside of the stator core and a winding winded on outside of the insulating bushing, the stator core is formed by stacking and rolling a linear iron core punching sheet, the stator core comprises punching sheet groups, each punching sheet group comprises a first punching sheet body, a second punching sheet body, a third punching sheet body and a fourth punching sheet body, each punching sheet body comprises an independent insulating bushing, the winding comprises an outer winding and an inner winding arranged on the radial inner side of the outer winding, the outer winding winds the adjacent first punching sheet body, second punching sheet body and third punching sheet body as one, and the inner winding winds the adjacent third punching sheet body, fourth punching sheet body and first punching sheet body as one. According to the technical scheme of the invention, the material utilization rate of the stator core punching sheet is improved, the dosage of winding enameled wire is reduced, the manufacturing process is simplified, the production efficiency is improved, the reliability of motor quality is good, and the cost is low.

Description

technical field [0001] The invention relates to the field of single-phase asynchronous AC motors, in particular to a novel single-phase asynchronous AC motor stator structure. Background technique [0002] At present, the stator structure of single-phase asynchronous AC motors basically adopts distributed windings + circular stator cores. The windings are embedded in the core slots by manual or machine insertion, and then the wire package is shaped, lead wires are connected, windings are bound, and finally the stator Dip paint. This kind of stator structure has many processes in the production process, requires a lot of manual operation, and the operation is troublesome for employees. The utilization rate of the circular iron core silicon steel sheet is low, and there are many hidden dangers in quality and difficult to manage. It cannot greatly reduce production costs and improve product competitiveness. Contents of the invention [0003] The technical problem to be solve...
