Furnaces with variable-speed blower motors are becoming more popular - no question about it. The benefits include electrical efficiency because a variable-speed motor consumes less energy than a ...

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% ...

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 ...

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 ...

“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.

PSC motors rely on the rotating magnetic field that is generated by the applied alternating voltage and corresponding alternating current to turn the rotor. The magnetic field rotates at 3,600 rpm (60 ...

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 ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...
