Field-oriented control optimizes industrial motors Design How-To 9/25/2006 Post a comment Variable-speed drives for three-phase motors are ubiquitous components of industrial systems that help save energy and optimize performance. Traditional, scalar control techniques for variable-speed operation of three-phase electric motors offer simple implementation but limit the achievable performance. With a scalar drive, algorithm limitations can mean that meeting dynamic response specifications requires choosing a larger motor and a larger drive to complement it. That tends to drag down eff
Energy harvesting: A battle against power losses Design How-To 9/24/2006 1 comment Can we design indefinite operational life and wireless power grids? Micro-scale harvesters can only generate low-to-moderate power, so that's a problem but low frequency ambient vibrations are relatively abundant. Here's what the power mechanisms are in a harvester circuit.
