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.

Motors are driving demand for electricity, accounting for about half of the electricity we consume, according to the Electric Power Research Institute (EPRI). Many of these motors are found throughout ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Another method worth considering in any discussion of motor control isvector control. The detailed formulation of this method to control thetorque and flux in PMSM was originally achieved by Jahns, ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

First note - I am a completely new to water cooling, this is the first build I've done. With GPU prices the way they are, I decided to try for an overclock vs a new GPU. Things are working well, and I ...

Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...
