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 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.

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...

Variable speed control of a compressor motor significantly reduces both the peak and average energy consumption. However, since the standards for air conditioners require a reduction in the seasonal ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

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 ...

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 ...
