초록

Recently PMSM(Permanent magnet synchronous motor) are used for the various direct drive
applications such as index table, telescope system and so on. Because the position/speed control
performance of direct drive PMSM is directly affected by the torque ripple, there are lots of
studies to reduce the cogging torque in the motor design stage. In order to verify the motor
design, the reliable cogging torque measurement system is essentially required. The measured
motor must be rotated in the constant speed under 1deg/sec so that the cogging torque profile is
measured correctly. In this study, the cogging torque measurement system which uses the direct
drive PMSM and the speed controller to rotate the measured motor in 0.1rpm(0.6deg/sec) has
been developed. Simulink/xPC target was used for the controller and data acquisition system.
Based on PI controller, DOB and AFC have been applied to eliminate the low frequency
disturbances and the periodic speed ripple. The experimental results show the good performance
of the speed regulation for the reference speed 0.1rpm and the reliable profile of the measured
cogging torque by the developed speed controller.
