Анализ возможностей снижения энергопотребления малогабаритных вентиляторов

A new construction of a single-phase asynchronous motor fan's drive in air discharge purification systems is proposed. This construction provide 25 per cent gain. In this paper we show that resonant mode better (based on power units) than other semi-parametric adjustable methods of changing the speed of asynchronous motors.
