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 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 ...

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 ...

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 ...

In hydronic heating and cooling systems, circulator pumps move water or refrigerant throughout a closed-loop system in order to transfer energy from the source to the point of need. While older ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

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 ...

Through legislative and social pressures, public attention is focusing more on the energy used to perform basic domestic functions such as food preparation, cleaning, and climate control.

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 ...
