220V AC Cooling Fan motor drive

"220V AC Cooling Fan" thanks to the brush less DC motor drive, no electromagnetic interference, completely overcome brush-commutated motor electromagnetic interference, noise, short mechanical life shortcomings, has been widely used in electronic, electrical and other required forced cooling applications. "220V AC Cooling Fan" motor for current frequency PWM pulse width modulation by the way, so that the operating efficiency of the brush less DC motor is greatly improved, can save half of the power supply. "220V AC Cooling Fan" motor strong impetus to retrofit fan performance, adds life to a new era of smart pen.
