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

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
