Embodiment Construction
[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] Problems that arise when the servo motor is running. During the normal operation of the servo motor, Q=I 2 Rt shows that the stator winding will generate a lot of heat. Since the motor is of a sealed structure, only a small amount of heat will be dissipated through the casing 20, and a large amount of heat will be stored in the cavity inside the motor for...

The invention provides a cover body structure, a motor, a compressor and an air conditioner, the cover body structure comprises a cover body, the cover body is internally provided with a cavity, a first side surface of the cover body is provided with an opening communicated with the cavity, the first side surface surrounds at least part of the opening, and the first side surface is provided with at least one recessed groove structure; the first side face can be connected with a motor shell in a matched mode, the cover body enters the motor shell through a gap between the cover body and the sealing gasket when external air passes through the cover body, water vapor in the air can flow back and forth in the groove structure for a short time when being blocked by the groove structure, and the water vapor is high in humidity and water vapor density. And the water is easy to adhere to the wall of the groove structure so as to be separated from the air, so that the content of water entering the motor along with the external air is greatly reduced, the service life of the motor is prolonged, and the property loss is reduced.
Description
technical field [0001] The invention belongs to the technical field of sealing structures, and in particular relates to a cover structure, a motor, a compressor and an air conditioner. Background technique [0002] As a high-precision power output device, servo motors are widely used in robots, machine tools, packaging equipment, printing equipment, etc. In these applications, there will be high humidity and water working environments. In these working environments, it is necessary to consider the waterproof performance of the servo motor. The waterproof facilities of traditional motors mainly take into account the waterproofing of the outlet of the motor, while traditional waterproof structures such as figure 1 As shown, this traditional structure is prone to leakage in a high-pressure and high-humidity environment, allowing moisture to enter the interior of the motor, reducing the service life of the motor, and prone to internal circuit short circuits, resulting in safety...
