The drives allow users with a large installed base to get better performance from their existing systems, and to continue using DC technology while better aligning with modern AC advancements. They ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...

The ZXBM1004 predriver IC offers variable-speed control for single-phase brushless dc fans and blowers. Compatible with NTC thermistor, voltage, and PWM input signals, the device offers thermal ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

Demand is growing for appliances such as washing machines, refrigerators, and air conditioners to help improve domestic energy efficiency. Moving from conventional fixed-speed motors to variable-speed ...
