motor

Abstract

A motor comprises a shielding can, a stator, a rotor and a metal shell. The shielding can is made of an insulation material and comprises a first can body and a second can body, the first can body or the second can body is provided with a channel, the channel communicates the internal space of the shielding can with the external space, the channel comprises a retaining wall, and the channel and the retaining wall jointly form a wire outgoing duct. The stator comprises an iron core, and the iron core is arranged in the shielding can. The rotor is rotatably combined with the shielding can. The metal shell covers the shielding can and comprises a through hole, the periphery of the through hole has a hole rim, the through hole is communicated with the channel of the wire outgoing duct, and the retaining wall of the wire outgoing duct covers or shields a part of or the entire part of the hole rim of the periphery of the through hole. Therefore, the motor is low in manufacturing cost and assembly difficulty.

Description

technical field [0001] The invention relates to a motor, especially a motor with an isolation cover. Background technique [0002] Please refer to figure 1 A kind of existing motor 9 shown, this motor 9 can utilize a first cover body 911 and a second cover body 912 of the isolation cover 91 to cover components such as the stator 92 of the motor or the permanent magnet group 931 of the rotor 93, by Here, the isolation cover 91 can ensure that the internal components of the motor 9 are isolated from the outside world, so moisture or foreign matter can be blocked, so as to provide better moisture-proof or dust-proof effects for the internal components of the motor 9 . In addition, the motor 9 further includes a metal shell 94, so that the isolation cover 91 can be further accommodated inside the metal shell 94, so that the metal shell 94 can be used to provide better structural strength, thereby providing better protection effect. [0003] The stator 92 of the motor 9 include...

AI Technical Summary

Problems solved by technology

However, wrapping the wires with a sheath or an insulating tube increases the manufacturing cost of the motor

Moreover, the harness or insulating tube is prone to displacement during the motor assembly process, causing the assembler or the machine to adjust the harness or insulating tube to ensure that the harness or insulating tube is formed on the Between the wire and the metal shell 94, it may increase the difficulty of assembling the motor 9

[0005] In view of this, there is an urgent need to provide a further improved motor to solve the above-mentioned problems of the existing motor 9 such as "higher manufacturing cost" and "difficult assembly"
