Web1 nov. 2013 · Most EC motors will come with multiple speed control inputs, not as an option, but standard. The commutation circuit can easily accept inputs such as PWM, 4-20mA, and 0-10V linear, to control the speed typically in the range of 10% to 100%. The control side of the motor is a low voltage circuit separate from main power. WebLow Inrush Motor Starting Motor manufacturers face difficult design choices. Designs optimized for low starting current often sacrifice efficiency, power factor, size, and cost. With these considerations in mind, it is common for AC induction motors to draw 6 to 8 times their full load amps when they are started across the line.
