Problems solved by technology

Due to the use of circuit boards, the material cost of the motor increases. In addition, the circuit boards are installed on the insulating frame, which increases the height of the motor, makes the space volume of the motor larger, and the structure is not compact enough. Furthermore, in the process of motor transfer Among them, the circuit board has quality risks such as loose connection and winding disconnection.

Embodiment Construction

[0023] see in conjunction Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, an insulating frame is provided, including a frame body 1, an outer ring wall 11 extending axially along the end surface of the frame body 1 is configured, and the outer ring wall 11 has a The limiting groove 12 limits the power cord 100 . In this technical solution, a limit groove 12 is set on the outer ring wall 11 to limit the power cord 100, so that the structure of the motor becomes simpler and more compact, the size is smaller, the manufacturing cost of the motor is reduced, and the power cord is effectively avoided. , Loose connection between winding lead wires, winding disconnection and other quality problems. The limiting groove 12 can be, for example, a groove with a constriction structure. It can be understood that the size of the limiting groove 12 should match the wire diameter of the power cord 100, and it is best to be able to A transition or even an...

Abstract

The invention provides an insulating skeleton, a stator assembly and a motor. The insulating skeleton comprises a skeleton body, an outer ring wall extending along the axial direction is formed on theend face of the skeleton body, and the outer ring wall is provided with a limiting groove for limiting a power supply wire. According to the invention, the insulating skeleton, the stator assembly and the motor make the size of the motor smaller and the structure simpler and more compact, the manufacturing cost of the motor is reduced, and at the same time, the quality problems such as the looseconnection between the power supply wire and the winding lead-out wire, the broken winding wire and the like can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to an insulating frame, a stator assembly and a motor. Background technique [0002] At present, most of the windings of the external controller DC brushless motor and between the winding and the power line are the same as those of the motor with the built-in controller. They are connected through a circuit board. The board and the circuit board of the external controller motor have only undergone adaptive changes in size. Due to the use of circuit boards, the material cost of the motor increases. In addition, the circuit boards are installed on the insulating frame, which increases the height of the motor, makes the space volume of the motor larger, and the structure is not compact enough. Furthermore, in the process of motor transfer Among them, there are quality risks such as loose connections and broken windings on the circuit board. Contents of the in...
