WebAug 11, 2024 · An ECM engine, also known as a variable speed motor, is a significant advancement for air conditioners and furnaces. In layman’s words, an ECM motor reduces the overall electrical consumption of an AC or furnace while still assisting the maintenance of sufficient air flow through the device. WebHorsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. = 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp. The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation.
