Abstract

A heat dissipation device for a three-phase asynchronous motor includes a heat dissipation end cap, elliptical end cover and protective cover, the heat dissipation end cover is internally provided with a heat dissipation fan, and a three-phase asynchronous motor housing is arranged on one side of the heat dissipation end cover, At one end of that heat dissipation end cover far away from the three-phase asynchronous motor housing, an elliptical end cover is arranged on the cover body, and a protective cover is arranged on the outer periphery of the cover body close to one end of the three-phaseasynchronous motor housing, the heat dissipation end cover is close to the casing of the three-phase asynchronous motor and a cover body directly opposite to one end of the protective cover is provided with a plurality of air inlet holes, the air inlet holes are arranged in the cover body of one end of the heat dissipation end cover, the air inlet quantity of air is increased so as to ensure thecirculation of air and ensure a heat dissipation effect. The protective cover arranged on the outer periphery of one end cover of the heat dissipation end cover prevents water stains or dirt from entering the heat dissipation device through the air inlet hole and facilitates the taking of the heat dissipation device through the friction lines on the outer periphery cover body of the protective cover.

Description

technical field [0001] The invention belongs to the technical field of motor equipment, and in particular relates to a heat dissipation device for a three-phase asynchronous motor. Background technique [0002] Three-phase asynchronous motor is a kind of induction motor. It is a type of motor powered by simultaneous access to 380V three-phase AC power supply (phase difference 120 degrees). Since the rotor and stator of the three-phase asynchronous motor rotate in the same direction and different The rotating speed becomes rotation, and there is a slip, so it is called a three-phase asynchronous motor. After the stator is fed with current, part of the magnetic flux passes through the short-circuit ring, and an induced current is generated in it. The current in the short-circuit ring hinders the change of the magnetic flux, resulting in There is a phase difference between the magnetic flux generated by the part with the short-circuit ring and the part without the short-circuit...
