Abstract
Many servo applications require electrical drives showing a good torque performance without disturbing torque pulsations especially in the low speed range. Usually the improvement of the torque performance is obtained by constructional design.
This paper presents a method for optimizing the electrical power supply of brushless permanent magnet excited synchron motors. In automatically running calibration processes the current wave forms for suppressing the torque pulsations are calculated on a computer controlled motor test stand. Using an efficient processor, the current curve generator can be easily integrated into the software of the motor electronic.
