Problems solved by technology

[0002]At present, AC single-phase asynchronous motors are commonly used in the field of air-conditioning outdoor unit motors, mainly due to their advantages such as low cost and high reliability. With the improvement of requirements, ordinary AC single-phase asynchronous motors are gradually unable to meet the requirements of energy efficiency upgrades; while the use of DC products can fully meet the requirements of energy efficiency upgrades, but the control cost of DC motor products has increased significantly, resulting in product competitiveness. satisfy customer's request

Abstract

The invention provides a stator punching sheet, a stator core, a motor stator and a motor. The stator punching sheet comprises an inner-layer punching sheet (1) and an outer-layer punching sheet (2) which are separately designed, the inner-layer punching sheet (1) comprises a stator inner ring (3) and winding inner teeth arranged on the outer peripheral side of the stator inner ring (3), the outer-layer punching sheet (2) comprises a stator outer ring (4) and winding outer teeth arranged on the inner peripheral side of the stator outer ring (4), and the winding inner teeth can be connected with the winding outer teeth to form closed slots. According to the stator punching sheet, the closed slot of the stator can be manufactured, the energy efficiency loss caused by magnetic leakage of a product is reduced, and the energy efficiency of a motor is improved.

Description

technical field [0001] The present application relates to the technical field of motors, in particular to a stator punch, a stator core, a motor stator and a motor. Background technique [0002] At present, AC single-phase asynchronous motors are commonly used in the field of air-conditioning outdoor unit motors, mainly due to their advantages such as low cost and high reliability. However, with the development of the industry and the improvement of product energy efficiency requirements, ordinary AC single-phase asynchronous motors are gradually unable to meet energy efficiency upgrades. Although the use of DC products can fully meet the requirements of energy efficiency upgrades, the control cost of DC motor products has increased significantly, resulting in a decline in product competitiveness and unable to meet customer needs. Contents of the invention [0003] Therefore, the technical problem to be solved in this application is to provide a stator punch, a stator core...
