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- ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

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 ...

PALATINE, Ill. – SEPTEMBER 6, 2005 – Best-in-class motor control for up to 700 HP motors is now available in the new Telemecanique® Altivar® 71 variable speed AC drive from Schneider Electric. Dual ...

Smart ICs increasingly handle complicated schemes such as field-oriented control. It is no secret that any equipment that either heats or cools is coming under great scrutiny as governments ...

Abstract: A variable speed AC motor drive, fed by a 3-phase AC supply, often consists of a 3-phase bridge diode rectifier, a DC link capacitor and a pulse width modulated inverter. Recently, a new ...

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 ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

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 ...
