Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a high-sealed three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a common type of AC motor, widely used in industrial and household equipment. Its working principle is based on electromagnetic induction, and the rotating magnetic field generated by the three-phase AC power supply drives the rotor to rotate. The three-phase asynchronous motor needs to be connected to a three-phase AC power supply. The three-phase power supply provides three phases of voltage, and the phase difference generates a rotating magnetic field to drive the motor to rotate.

[0003] The prior art (Announcement No.: CN 214707366 U) discloses a three-phase asynchronous motor, comprising a housing, a stator disposed in the housing, and a rotor disposed in the housing, wherein the housing is provided with a support seat, the housing comprising a shell, an end cover disposed on the shell, and a cover disposed on the shell, wherein the end cover is integrally arranged with the shell.

[0004] Although the above patent reduces the noise generated by the vibration of the workpiece on the motor and reduces the processing cost, it has the following disadvantages: the sealing performance of the three-phase asynchronous motor is poor. When operating underwater, water can easily enter the interior of the motor, causing damage to the motor. Further improvement is needed. For this reason, we propose a highly sealed three-phase asynchronous motor. Utility Model Content

[0005] The main purpose of the utility model is to provide a highly sealed three-phase asynchronous motor, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A highly sealed three-phase asynchronous motor includes a motor housing, the right end of the motor housing is connected to a rear end cover, the interior of the motor housing is provided with a working chamber and a sealing chamber from left to right, the right end of the motor housing is provided with a plurality of first sealing grooves from outside to inside, and a sealing ring is provided in each of the plurality of first sealing grooves, the left end of the rear end cover is provided with a plurality of second sealing grooves from outside to inside, and the sealant enters the motor housing through the sealing chamber.

[0008] Preferably, the sealing cavity includes a glue pouring cavity, which is arranged in the motor housing and located on the right side of the connecting plate. A plurality of L-shaped grooves are provided on the inner wall surface of the glue pouring cavity. A glue injection tube is provided on the upper inner wall of the glue pouring cavity. The upper end of the glue injection tube extends to the outside of the motor housing, and a sealing cover is provided on the outer surface of the glue injection tube.

[0009] Preferably, the right ends of the plurality of sealing rings extend into the plurality of second sealing grooves.

[0010] Preferably, the outer cylindrical fixed sleeve of the motor housing is provided with a plurality of heat sinks.

[0011] Preferably, a fixing ring is installed on the right part of the inner cylindrical surface of the working chamber, and a connecting plate is fixedly connected to the right end of the fixing ring, and the connecting plate is located in the working chamber.

[0012] Preferably, the outer surfaces of the motor housing and the rear end cover are coated with a ceramic coating, and an insulating waterproof coating is provided on the ceramic coating.

[0013] Preferably, the motor housing is detachably connected to the rear end cover by bolts.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The sealing cavity can improve the sealing between the motor housing and the rear end cover. When in use, the sealing cover is opened and the sealant is injected into the sealant cavity to fill the gap between the motor housing and the rear end cover. This can effectively prevent water and moisture from entering the motor, protecting the motor from moisture damage, thereby extending the service life of the motor. At the same time, the L-shaped groove can fix the position of the sealant, preventing the sealant from shifting when subjected to pressure or vibration, thereby maintaining stable sealing performance.

[0016] The sealing performance can be further improved by setting multiple sealing rings. When in use, multiple sealing rings can provide multiple layers of protection. Each layer of sealing ring increases the safety of the seal, preventing liquid, dust, dirt and other contaminants from entering the motor interior, thereby improving the sealing effect. Even if one sealing ring fails, the other sealing rings can still continue to function, ensuring the long-term stable operation of the motor;

[0017] By setting a ceramic coating, the corrosion resistance of the motor housing and rear end cover can be improved, effectively preventing water penetration and corrosion, maintaining the integrity of the motor appearance and structure, and avoiding structural weakening or functional failure due to rust. By setting an insulating waterproof coating, moisture can be prevented from contacting the motor housing and rear end cover surface, protecting the motor housing and rear end cover from moisture damage, and ensuring the normal operation of the motor.
