Problems solved by technology

[0010] At present, in order to reduce the volume of the motor, the gap between the motor casing and the stator is often designed to be very small (<2.5MM). According to regulations, the distance between the wire and the casing 1 is greater than 2.5MM. Since the A1 hook is located on the stator insulation frame At the edge of 12, when the wire is wound through the A1 hook, the distance between the wire and the case 1 is less than 2.5MM, which is easy to generate withstand voltage, break down the case, and cause leakage

Abstract

The present invention belongs to a motor stator insulating frame structure, which comprises a stator insulating frame, a hook A1 and a hook A2 symmetrically formed on an edge of the stator insulating frame along a vertical centerline of the stator insulating frame, a hook B positioned on a stator insulating frame reinforcing stable on a right side of the hook A2, a first, a second, a third and a fourth wiring post table are arranged on the stator insulating frame. The insulating frame structure is additionally composed of a hook C between the second and the third wiring post table and at one end of a supporting rib of the wiring post table. Due to the hook C on the insulating frame, the structure changes lead winding rout and ensures a distance between the lead and a shell longer than 2.5mm, thus avoiding shell puncture due to voltage withstand and preventing power leakage.

Description

technical field [0001] The present invention relates to the stator structure of the motor, more specifically, to the motor stator insulating frame structure for changing the winding route of the wire. Background technique [0002] A general motor is a machine that converts electrical energy into kinetic energy. Such motors are divided into rotary motors that convert electrical energy into rotary motion and reciprocating motors that convert electrical energy into linear reciprocating motion. [0003] Motors are installed as power sources in almost all products used in households such as refrigerators, air conditioners, washing machines, electric fans, and vacuum cleaners. [0004] A conventional single-phase motor will be described as shown in FIG. 1 . [0005] FIG. 1 is an exploded view of the single-phase motor shown in the figure. As shown in the figure, the conventional single-phase motor includes a stator 2 formed by a laminated iron core wound with coils on the inside ...
