Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Pulse-width modulation (PWM) is an efficient method for controlling the light intensity of a lamp or the speed of a simple DC motor. It lets you take advantage of the load's inertia by switching the ...

Optimized for AC/DC power supplies in industrial applications, Rohm’s PWM controller ICs support a wide range of power semiconductors. Mass production has begun for four variants: the BD28C55FJ-LB for ...

You can divide the world of electronic motor drives into two categories: ac and dc. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. A dc drive typically ...

With the global trend toward green power and affordable energy gaining momentum, applications such as home appliances, lighting, and power tools, as well as other industrial equipment and ...
