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 ...

The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...

Four stock controls from Bodine Electric provide reliable speed control for low-voltage 12 V (Models 0786 and 0787) or 24 V (Models 0788 and 0789) PMDC gearmotors and motors (up to 1/3 HP/250 W). Four ...

International Rectifier has filled the last gap in its motor control portfolio with a pair of controller chips. The firm now produces controllers, power Mosfets, IGBTs and high voltage driver chips.

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...
