September 2005[Point of View] Electric Avenue—Getting The Speed Controls In Place
Today, much of the electricity on the planet is consumed by inefficient electric motors from a bygone era. It is estimated that over 50% of all electricity is directed at powering motors that feature simple mechanical controls rather than electronic control advances. The refrigerator operating in many kitchens today is a good example. It uses a bi-metallic switch to turn the motor on when the inside temperature gets too hot, and then turns it off when the desired temperature is...
May 2005[Cover Feature] Power Driver Scores A Whole In One
Variable-speed drives are the future for energy-efficient operation of electric motors for domestic appliance and industrial servo applications. However, conventional, discrete implementations cannot deliver the cost and size reductions necessary to ensure their widespread market acceptance. To deliver considerable energy savings, variable-speed motor drives must perform more sophisticated functions than their predecessors, including IGBT protection and linear current feedback...
