Abstract
The utility model discloses a kind of steady control circuit for high-rise building air pipe motor, comprise K switch and the motor M of power supply AC and series connection mutually, also comprise the first voltage stabilizing didoe D1 and the second voltage stabilizing didoe D2 of triode Q1, the first resistance R 1, the second resistance R 2, the 3rd resistance R 3, capacitor C and differential concatenation.The utility model has strengthened the antijamming capability of whole circuit, realizes the stable control of motor K, thereby makes whole high-rise building air pipe ventilation effect more stable.
Description
Technical field
The utility model relates to electric machines control technology field, is specially a kind of steady control circuit for high-rise building air pipe motor.
Background technology
Along with the continuous quickening of urbanization process in all parts of the country, high-rise building is rised sheer from level ground like the mushrooms after rain.Wind wheel circuit for controlling motor in high-rise building air pipe is relatively simple for structure at present, due to the aerial electromagnetic environment more complicated of height, so existing high-rise building air pipe machine operation environment is more severe, operation is got up very unstable, and then affects high-rise building air pipe ventilation effect.
Utility model content
The purpose of this utility model is to provide a kind of steady control circuit for high-rise building air pipe motor in order to overcome above-mentioned deficiency.
The utility model comprises K switch and the motor M of power supply AC and series connection mutually, also comprise triode Q1, the first resistance R 1, the second resistance R 2, the 3rd resistance R 3, the first voltage stabilizing didoe D1 of capacitor C and differential concatenation and the second voltage stabilizing didoe D2, described the 3rd resistance R 3 and capacitor C parallel connection, the branch circuit parallel connection of described capacitor C and K switch and motor M, the positive pole of described power supply AC is connected with the base stage of triode Q1, one end of described the first resistance R 1 is connected to the emitter of triode Q1, the other end of described the first resistance R 1 is connected to the positive pole of the first voltage stabilizing didoe D1, one end of described the second resistance R 2 is connected to the collector electrode of triode Q1, the other end of described the second resistance R 2 is connected to one end of the 3rd resistance R 3, also be connected to one end of capacitor C and one end of K switch simultaneously, the negative pole of described the first voltage stabilizing didoe D1 is connected with the negative pole of the second voltage stabilizing didoe D2, the positive pole of described the second voltage stabilizing didoe D2 is connected with the negative pole of power supply AC, the other end of described K switch is connected with one end of motor M, the other end of described the 3rd resistance R 3, after the other end parallel connection of the other end of capacitor C and motor M, be connected to the negative pole of the second voltage stabilizing didoe D2.
The utility model has been abandoned original multipath isolated power module scheme, adopt the 3rd resistance R 3 and capacitor C parallel connection to prevent that motor K two terminal potentials from occurring to change suddenly, the second resistance R 2 and capacitor C have played the effect of low-pass filtering simultaneously, the second resistance R 2 has also played the effect of current-limiting protection, the first voltage stabilizing didoe D1 of differential concatenation and the second voltage stabilizing didoe D2 and the first resistance R 1 play auto_steady amplitude jointly, strengthen the antijamming capability of whole circuit, realize the stable control of motor K, thereby make whole high-rise building air pipe ventilation effect more stable.
