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 ...

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 ...

These variable speed drives (VSDs) were developed to avoid the additional equipment and maintenance requirements associated ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

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 ...

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 ...

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 ...

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 ...

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.
