[0002] The three-phase asynchronous motor is a device that provides driving power for various equipment. Its main function is to use the current-carrying rotor conductor to generate electromagnetic force under the action of the stator rotating magnetic field, thereby forming an electromagnetic torque on the motor shaft to drive the motor to rotate. It is an indispensable device in existing motors; the existing three-phase asynchronous motors have certain disadvantages when in use. First, the three-phase asynchronous motor is not convenient when replacing internal components or repairing and maintaining, and it is time-consuming and laborious to disassemble and install. It is also not convenient to support and fix the three-phase asynchronous motor, and the supporting feet are not convenient to store. In addition, the three-phase asynchronous motor generates large noise and vibration, which greatly affects the user experience.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] A power socket is fixedly installed inside the junction box 3, and the output end of the junction box 3 is electrically connected to the input end of the rotor 15 and the cooling fan 16; the outer surfaces of the end cover 5 and the waterproof cover plate 7 are coated with an anti-oxidation coating, and the end cover 5 is movably connected to the motor body 1; a spring shaft is fixedly installed on the upper end of the storage shock-absorbing support foot 12, and an anti-slip pad is provided at the lower end of the storage shock-absorbing support foot 12; dustproof nets are provided inside several groups of heat dissipation holes 13, and the shape of the heat dissipation holes 13 is wide strip-shaped; the outer surface of the rotating shaft 19 is coated with a lubricating coating, and the rotating shaft 19 is movably connected to the bearing 18.

[0021] It should be noted that the present invention is a low-power three-phase asynchronous motor. When in use, the terminal box 3 fixed by the fixing bolts 14 on the motor body 1 is first connected to the power supply. The rated power of the terminal box 3 is small, so that the power of the motor is small, thereby saving more electricity. After the motor is powered, the rotor 15 generates electromagnetic force under the action of the rotating magnetic field inside the motor body 1, thereby forming an electromagnetic torque on the rotating shaft 19 to drive the motor to rotate. The heat dissipation ribs 2 cooperate with the heat dissipation fan 16 inside the cover shell 6 and the heat dissipation holes 13 on the surface to better dissipate heat for the motor. The fixing block 9 can better fix the motor on the motor base 10 to prevent displacement. The metal lifting ring 8 can conveniently carry the motor. When the internal components of the three-phase asynchronous motor need to be repaired, maintained or replaced, the metal fixing buckle 11 only needs to be opened, and then the motor body 1 can be removed from the motor base 10, which is very time-saving and labor-saving. When the motor needs to be supported, the storage shock-absorbing support foot 12 can be bent out from the storage groove 20 with the spring shaft at its upper end, which is very convenient to use. The noise reduction and sound insulation board 17 is made of low-density board material, and a layer of new polymer material is compounded between the two boards through a special process to achieve the effect of noise reduction and sound insulation, which is very convenient and practical. The motor nameplate 4 clearly marks the various parameters of the motor, which is convenient for users to read.
