New Developments in Commutation and Motor Control Techniques
"New Developments in Commutation and Motor Control Techniques" talks about the recent activity around the use of advanced current control techniques, especially field oriented control (FOC). Because of its potential for lower energy consumption and performance, this technique for controlling brushless DC and AC induction motors has become a focus of the motion control industry. Chuck Lewin states that FOC is a significant improvement over standard variable speed drive techniques for AC induction motors.
