I've been watching a discussion on a LinkedIn group that is addressing some writers' concerns about variable speed drives (VSD). The discussion is titled “Are variable speed drives harmful to motor?

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 ...

Sleek, streamlined and compact LV Titanium Variable Speed Motor platform enables fast-track, one-person installation with reduced cabling and no commissioning to cut setup costs and reduce material ...

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% ...

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 ...

Chances are, the HVAC system in your house uses a single-speed induction motor to power its fan, and the Department of Energy (DOE) wants to change that. The nation’s energy watchdog wants to replace ...

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, 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 drives are transforming modern irrigation by shifting control from valves to pump speed. Instead of running motors at full capacity and throttling flow, the drives adjust motor speed to ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
