Global demand for both energy and water conservation is having a tremendous impact on the home appliance market. The regulatory standards and recommendations are redefining a new generation of energy- ...

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 Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

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 ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

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 ...

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 ...

When the Washington State Ferry System selected a synchronous, variable-speed AC motor with a cycloconverter drive for the propulsion system on its three new Jumbo Mark II ferries, the ships became ...
