The invention discloses a cooling and noise reduction structure of a three-phase asynchronous motor. The cooling and noise reduction structure comprises a shell, the left end of the shell is fixedly provided with a first left end cover through welding, the first left end cover is used for protecting internal parts of the three-phase asynchronous motor, and the center position of the first left end cover is fixedly provided with a rotating shaft. The rotating shaft is a main working part of the three-phase asynchronous motor, a second left end cover is fixedly installed at the tail end of the left side of the shell through threads, the second left end cover has the effects of dust prevention, collision prevention and personal safety protection, a plurality of motor supports are fixedly installed on the lower surface of the shell through welding, the motor supports are used for supporting the three-phase asynchronous motor, a mounting bottom plate is fixedly mounted at the other ends of the motor supports through threads and used for fixing and connecting the three-phase asynchronous motor, and a base box is fixedly mounted between the lower surface of the bottom of the shell and the mounting bottom plate. The cooling fan and a special structure help the three-phase asynchronous motor to carry out cooling and noise reduction treatment.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a temperature-reducing and noise-reducing structure of a three-phase asynchronous motor. Background technique [0002] At present, the three-phase asynchronous motor is a type of motor that is powered by a 380V three-phase AC power supply (with a phase difference of 120 degrees) at the same time. Since the rotor and the stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there are Slip, so it is called a three-phase asynchronous motor. The three-phase asynchronous motor is an induction motor. After the stator is fed with current, part of the magnetic flux passes through the short-circuit ring and induces current in it. The current in the short-circuit ring hinders the change of the magnetic flux, resulting in a phase difference between the magnetic flux generated by the part with the short-circuit ring and the...
