Problems solved by technology

[0007] However, the insulating sheet with such a structure has the following problems. The two ends 4 of the connecting strip 3 are as thick and thin as the main body, and the connecting strip 3 as a whole has a rectangular shape.
In this way, the area of ​​the welding part between the upper piece, the lower piece and the connecting strip is small. When installing the insulating sheet, when the insulating sheet is under too much force, the connecting strip is easy to break at the welding place, resulting in waste products, which increase the waste products and improve production efficiency. decline

Embodiment Construction

[0021] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0022] FIG. 2 is a schematic diagram of the insulating sheet of the present invention. As shown in the figure, the insulating sheet of the present invention is composed of an upper sheet 1 , a lower sheet 2 and a connecting strip 3 . The upper sheet 1 is a shape in which two fan shapes are connected together, and a bow-shaped notch is formed at its left and right lower corners, and a notch is formed at the welding place at its lower end. The lower piece 2 is a shape in which two quadrilaterals are connected together, the lower end of the quadrilateral is arc-shaped, and the upper end of the lower piece has a gap at the weld. The connecting bar body 3 is rectangular, and its two ends 5 are fan-shaped. The upper sheet, the lower sheet and the ...

Abstract

The invention belongs to insulated object which is used in brushless direct current motor, especially an insulated piece of motor winding loop which is used brushless direct current motor. Insulated piece made by plastic includes upper piece, lower piece and connecting bar. The connecting bar is rectangle, two ends are sector. Two ends of the connecting bar are welded by the upper piece and the lower piece to make the three parts an integral. Because two ends of the connecting bar is sector, so the welded area is expended, the insulated piece can not be ruptured, production efficiency is increased.

Description

technical field [0001] The invention belongs to an insulator used for insulation in a motor, in particular to an insulating sheet for a motor winding coil used for DC brushless motor coil insulation. Background technique [0002] The motor is usually the core drive source of most home appliances such as compressors, washing machines, and electric fans. Brushless DC motor is a motor that uses electronic rectifiers instead of brushes and commutators in DC motors. It not only has a series of advantages such as simple structure, reliable operation, and convenient maintenance of AC motors, but also has high operating efficiency and no Excitation loss and good speed regulation performance can not only avoid mechanical noise but also avoid electrical noise and many other characteristics. Widely used in various fields of the national economy including household appliances. [0003] The motor is mainly composed of a stator and a rotor. The stator has an independent coil structure, ...
