First creation, National patent-Designed by Kaidisen    

    Brushless DC stepless motor K90WZD/S series--except the all applicable Chinese traditional hood efficacy ,also have the following advantages.
1.free speed regulation
    Random speed can adjust according to the volume of lampblack, solve traditional lampblack machine's simple speed defects,truly continuously variable automatic transmission.
2.Ultra low noise
    Low speed air noise is within 30 db--ultra quiet, low vibration, let your life more quiet.
3.High efficiency and energy saving
    It costs 5w only when motor operating speed is 300 rpm/min .It costs RMB five cents only for 24 hours in a day, It saves 50% power with high-speed exhausting. Energy conservation and environmental protection,give you a low consumption and clean kitchen back.
4.High pressure
    Static pressure, maximum static pressure increase by more than 60%, smoke channel wall motor power automatically improve, improve the exhaust, "absorb" force increased by more than 50%, unimpeded.
5.Perfect appearance   
    Motors are all used high performance quality materials,  aluminum enclosure, volume decreased 25%, reduce wind blocking, increase the "row" air volume.

The controller supply voltage is 220V,the motor's rated DC voltage is 310V. The rotation speed can be adjusted from 300 to 1800r/min arbitrarily.

The motors can be customized according to different voltage,frequency,size and rotation speed.
