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 ...

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 ...

Developed by Farnell element14, the S12ZVML-MINIBRD variable speed motor control kit is based on the Freescale S12 MagniV. It includes both the hardware and software needed to get a variable speed ...

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 ...

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 ...

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 ...

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 ...

IR-SA Integrated Technologies, a collaboration between International Rectifier (IR) and Sanyo Semiconductor, will design, develop, and market variable-speed motor-drive power modules. These products ...

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, ...

Washing machines, refrigerators, dishwashers, air conditioners, and other appliances sell more on their "green" credentials, like a high-energy-efficiency rating, than other factors. The use of speed ...

Upgrades that included a constant-torque flux-vector variable-speed motor let a pre-1912 vintage stamping press handle modern production duties. The rebuilt press was refurbished with new ac-drive ...
