A recent world-wide interest in the environmental friendliness, water consumption, and energy saving particularly impinges on the home appliance area. The actual regulatory standards and ...

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 ...

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 ...

While advanced field-oriented control enables the use of compact permanent-magnet motors, reductions in drive electronics are also possible when a single controller manages dual motors. Appliance ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

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 ...
