Problems solved by technology

Specifically, the two ends of the conductive tape are respectively bonded to the bearing brackets on both sides. In this way, the electrical connection of the bearing brackets on both sides can be realized through the conductive tape, which can alleviate the electric corrosion of the bearings to a certain extent. There are still the following deficiencies in the application: 1) The installation and fixation of the conductive tape is realized solely by the bonding of the conductive tape and the bearing bracket, and the stability and reliability of the installation is low; 2) In order to realize the bonding of the conductive tape

Example Embodiment

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0032] It should be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is said to be "connected" to another element, it can be directly connected to the other element or a central element may be present at the same time. It should also be noted that the orientation terms such as left, right, up, down, top, and bottom in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be considered a...

Abstract

The invention is applicable to the motor filed and discloses a motor. The motor comprises a stator assembly, a circuit board, a first bearing rack and a second bearing rack as well as an insulation support and a metal conductive component, wherein the first bearing rack and the second bearing rack are arranged on two sides of the stator assembly respectively; the insulation support is mounted on the stator assembly, the metal conductive component is fixed on the insulation support, two ends of the metal conductive component are electrically connected with the first bearing rack and the second bearing rack respectively, a positioning column is arranged on the insulation support, a positioning hole is formed in the circuit board, the circuit board is supported on the insulation support, and the positioning column penetrates through the positioning hole. According to the motor, electrical connection between the first bearing rack and the second bearing rack is realized by the aid of the arranged metal conductive component, and the longtime effectiveness of the electrical connection between the first bearing rack and the second bearing rack is guaranteed; meanwhile, lock fixing of the metal conductive component can be realized by the aid of the arranged insulation support, the circuit board can be supported and positioned, and the used parts of the motor are reduced.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a motor. Background technique [0002] Conventional plastic-encapsulated brushless DC motors generally have the problem of electric corrosion of bearings. In order to solve this technical problem, the prior art proposes a technical proposal of installing conductive tape between the bearing brackets on both sides. Specifically, the two ends of the conductive tape are respectively bonded to the bearing brackets on both sides. In this way, the electrical connection of the bearing brackets on both sides can be realized through the conductive tape, which can alleviate the electric corrosion of the bearings to a certain extent. There are still the following deficiencies in the application: 1) The installation and fixation of the conductive tape is realized solely by the bonding of the conductive tape and the bearing bracket, and the stability and reliability of the installation is low; 2) In orde...
