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 ...

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 ...

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 ...

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 topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

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% ...

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 ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...

ELECTRONICS: DynaMotors Inc announced its first production motor in a new family of single-phase variable-speed electric motors for air moving, pumping, woodworking machinery, and other commercial ...
