In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

Over 50% of Earth’s total electricity consumption is used for operating motors and motor systems. HVAC contractors and technicians encounter motors in a variety of different applications, and aspects ...

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 ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

As a hybrid technology that combines mechanical and electrical systems, electrohydraulic variable speed drives allow for motor speed adjustments to conserve energy and provide precise control over ...

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 ...

In hydronic heating and cooling systems, circulator pumps move water or refrigerant throughout a closed-loop system in order to transfer energy from the source to the point of need. While older ...

“A bunch of things are coming together.” That's how V Sukumar, a senior applications manager for Fairchild Semiconductor, begins a discussion of trends in motor control for the white-goods market.
