Design and Experimental Results of a Brushless AC Servo Drive

摘要: High-quality electrical servo drives can only be designed and manufactured by using especially compatible sophisticated components. A typical control actuator system is described consisting of a brushless synchronous motor transistor chopper inverter. Important aspects the design rating three-phase with rare-earth permanent magnets are pointed out. Several types construction described. The machine used familiar method cascade control. By application "space vectors" two special methods for fast response current developed. In first case, inverter signals derived from measured quantities. second optimum controller output calculated if additional information about controlled exists. Finally, experimental results prove excellent performance this drive system.
