Because must carry on the competition in the market, there is no manufacturer is willing to put into the development of this product, our factory has developed for more than a year, only to do a few batch of orders to the foreigner, can't sell in China.
Ac motor cheap and long service life (up to only five years), but only for a hotel, office buildings and other projects, a lot of people think the products have passed 3 C certification, not a security issue, if not these products manufacturers of professional personnel to install, can pose a safety hazard, because they don't understand the internal structure of electric curtain motor, such things don't happen again.
Electric curtain commonly USES ac motor is the best, the ac motor is torque big, such as electric curtain of electric, electric curtain of electric curtain, shutter, Roman curtain, ceiling shade, etc. But now partial open curtain motor is involved in power failure manual function, dc motor voice is very small, adopt direct current electric control method. The performance aspect is also stable. The curtain machine should be selected according to the actual needs. Note that the quality of regular manufacturer is reliable.
