Embodiment Construction

[0032] see in conjunction Figure 1 to Figure 7 As shown, according to the embodiment of the present application, a motor sealing assembly is used to seal the wire hole through which the wire 3 passes between the stator 1 and the end cover 2, including:

[0033] The sealing member 4 includes a connecting bridge 41, and the connecting bridge 41 spans the wire 3 in a bridge type;

[0034] The connection bridge 41 includes a first side 412 and a second side 411 , the first side 412 is in sealing contact with the wire 3 , and the second side 411 is in sealing contact with the end cap 2 .

[0035] Based on the fact that when the wire 3 passes through the wire hole between the stator 1 and the end cover 2, there will be a large gap between the wire 3 and the end cover 2, the application adds a bridge across the wire 3 at the gap. The sealing member 4 is provided with two side surfaces on the connecting bridge 41 included in the sealing member 4, and is in sealing contact with the w...

Abstract

The invention provides a motor sealing assembly and a motor. The motor sealing assembly is used for sealing a wire passing hole, through which a lead wire penetrates between a stator and an end cover, and comprises a sealing element which comprises a connecting bridge spanning the lead wire in a bridge manner, wherein the connecting bridge comprises a first side surface and a second side surface, the first side surface is in sealing contact with the lead wire, and the second side surface is in sealing contact with the end cover. By arranging the sealing element in the gap, the sealing performance of the PG motor is improved, the protection of the motor is enhanced, tiny organisms and particles are effectively prevented from entering the PG motor, and the potential safety hazard of the PG motor used in tropical areas is reduced. The structure of the motor sealing assembly is simple to install, not prone to loosen, good in producibility and reliability, and easy to popularize and use.

Description

technical field [0001] The application belongs to the technical field of motors, and in particular relates to a motor sealing assembly and a motor. Background technique [0002] As the domestic air conditioner market expands overseas, many air conditioners are exported to tropical countries or regions such as Thailand and India. PG motor is a household air conditioner AC plastic-sealed motor that uses thyristor to regulate speed. It is mainly composed of plastic-sealed stator, Hall assembly wire, rotor, end cover, etc. Usually, there is a slot on the plastic-enclosed stator to lead out the power line of the Hall component, and an unsealable gap is formed between the end cover, the plastic-enclosed stator, and the wire of the Hall component. The gap usually appears between the wire of the Hall component and the end cover. between, such as Figure 8 As shown, the tightness of the PG motor is poor. In some tropical areas, some tiny insects and particles can easily enter the m...
