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 ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

A line of brushless DC (BLDC) motor control ICs contain 115 Vac and 230 Vac devices that integrate six IGBT bridges for fractional and subfractional HP BLDC motors. With complementing bridge drivers, ...

The 15 series enclosed Digital Speed Controller from Dart Controls is available in open or closed chassis styles and NEMA 1 ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

If you run your variable frequency drives at 60 Hz and below, you are not alone. Nearly all the VFDs in North America operate below this nominal frequency threshold. Yet a growing number of ...
