“A bunch of things are coming together.” That's how V Sukumar, a senior applications manager for Fairchild Semiconductor, begins a discussion of trends in motor control for the white-goods market.

Variable speed motor controllers regulate the speed and/or torque of asynchronous motors. Depending on the application, there are controllers from a few hundred Watts up to several hundred Kilowatts.

Model VSM-CA3 modulates the speed of motors in fancoil units, fan-powered VAV terminal units, fan filter units, and other air-moving devices. The controller provides modulating control of AC induction ...

Energy conversion efficiency has always played an important role in electronics design, and in the case of electric motors, the conversion takes place twice: first to create the electricity needed to ...

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 ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

The motor system can be considered at three levels: motor behaviour, limb mechanics and neural control. Although our understanding at each level continues to grow, linking these levels into a cohesive ...
