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?

A recent world-wide interest in the environmental friendliness, water consumption, and energy saving particularly impinges on the home appliance area. The actual regulatory standards and ...

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% ...

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 ...

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 ...

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 ...

The amount of energy saved by using variable speed motor drives adds up to a greener world, says David Tam of International Rectifier From home appliances to industrial control applications, ...

Applications requiring variable speed control, precision performance with low torque ripple, and high power in a compact, 1.73'' in diameter package are said to represent the primary market for NT ...

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 ...

ON Semiconductor has introduced a motor development kit for motors up to 4kW, and soon to 10kW. “In order to improve efficiency, ac induction motor drives designers must understand how these and other ...
