Description
Technical field
The utility model relates to motor technology field, particularly relates to a kind of three-phase asynchronous motor being applicable to wet environment.
Background technology
Make the phase asynchronous motor of motor running. The rotating speed of three-phase asynchronous motor rotor is lower than the rotating speed of rotatingfield, and rotor windings produces electromotive force and electric current because there is relative movement between magnetic field, and produces electromagnetism torque with magnetic field interaction, it is achieved energy evolution.
Compared with single-phase asynchronous electric motor, three-phase asynchronous motor operating performance is good, and can save various material. By the difference of rotor structure, three-phase asynchronous motor can be divided into cage and Wound-rotor type two kinds. The Induction Motor Structure of cage rotor is simple, reliable, weight is light, price is cheap, is widely used, and its main drawback is speed governing difficulty. The rotor of wound three-phase asynchronous motor is the same with stator to be also provided with three-phase windings and is connected with outside varistor by slip ring, brush. Regulating rheostat resistance can improve the starting performance of electric motor and regulate the rotating speed of electric motor.
In prior art, three-phase asynchronous motor uses for a long time in the environment of humidity, is easy to make internal condensate water droplet, causes internally charged components and parts to burn damage, thus whole electric motor is scrapped, waste ample resources and cost.
Summary of the invention
In view of this, it is necessary to a kind of three-phase asynchronous motor being applicable to wet environment is provided.
The utility model realizes like this, a kind of three-phase asynchronous motor being applicable to wet environment, comprise motor casing and rotor, one end of described rotor connects the movement being in motor casing inside, the other end is extremely outside through the sidewall of motor casing, also comprise the first dividing plate, second partition, water-absorbing sponge, humidity sensor and warning horn, described first dividing plate and second partition are installed on the inwall of described motor casing, and it is all parallel with described sidewall, and rotor is through described first dividing plate and second partition, described rotor and sidewall, it is equipped with rubber seal between first dividing plate and second partition, described sidewall, first dividing plate and second partition are parallel to each other, separate space between having first between described first dividing plate and described sidewall, separate space between having the 2nd between described first dividing plate and second partition, described water-absorbing sponge is located in described first separate space, and it is fixed on the inwall of motor casing, described humidity sensor and warning horn be all located at the described 2nd between in separate space, and humidity sensor is electrically connected with described warning horn.
The advantage of a kind of three-phase asynchronous motor being applicable to wet environment that the utility model provides is: the utility model is simply rational in infrastructure, by arranging the first dividing plate, second partition, water-absorbing sponge, humidity sensor and warning horn, when wet environment uses, steam is stopped by rubber seal, even if after minority enters first separate space, absorbed by water-absorbing sponge, after long-time use, first separate space moisture is saturated, steam enters the 2nd separate space, trigger humidity sensor, humidity sensor starts warning horn and carries out alarm, even if prompting serviceman's process and maintenance, effectively extend the work-ing life of electric motor, and motor interior band electrical component can not be made to burn, improve safety performance.
