Description

TECHNICAL FIELD

[0001] The utility model relates to motor waterproof technical field, especially relate to a fan blade formula water seal cover and end cap subassembly thereof. BACKGROUND

[0002] In the actual application scene of the motor, especially in the motor running in outdoor or humid environment, waterproof performance becomes the key factor affecting its stability and service life. Taking vertical motor as an example, its unique structure and working mode make it more vulnerable to water during operation.

[0003] Traditional motor waterproof measures are mostly simple sealing rubber ring or waterproof cover. However, these methods have many limitations. On the one hand, the sealing performance of the sealing rubber ring will gradually decrease after long-term use, affected by factors such as vibration, temperature change and water erosion during motor operation, leading to water infiltration into the motor, and then causing short circuit, corrosion and other faults, seriously affecting the normal operation of the motor. On the other hand, ordinary waterproof cover can only block the external water splash to a certain extent, and has no effect on the centrifugal force generated by the motor during operation, which will throw water to the motor end cover. When the motor end cover has water, the water will slowly penetrate into the motor through the motor shaft or other gaps, causing damage to the key components such as winding and core of the motor.

[0004] In addition, in some special application environments such as mining, metallurgy and chemical industry, the motor not only has to face a lot of water, but also has to contact with liquid containing corrosive substances. The existing waterproof structure cannot effectively resist these corrosive liquids, resulting in further reduction of the waterproof performance of the motor, substantial increase of maintenance cost, extension of equipment downtime and huge economic loss to the enterprise.

[0005] With the rapid development of industry, the requirement for the waterproof performance of the motor is getting higher and higher, and there is an urgent need for a technical solution that can effectively improve the waterproof effect and ensure the long-term stable operation of the motor in harsh environment.
