This paper presents an analytical study on the mid-frequency resonance phenomenon of step motors. This phenomenon is frequently observed as pronounced oscillations when a step motor is driven by usual open loop drive method at relatively high input pulse rate. Since the phenomenon causes torque drop or torque dip in the torque-speed curve of the motor, it limits the possible operations of the motor system. The purpose of the study is toinvestigate the mechanism of the phenomenon in permanent-magnet step motors. A method to predict the behavior of the motors in the mid-frequency resonance is presented. This method is based on a kind of harmonic analysis. The amplitude and the frequency of the velocity oscillations of the motor in the mid-frequency resonance can be calculated by the method. These theoretical predictions show fairly good coincidence with the experimental results. And the characteristics of the mid-frequency resonance can be explained by the analysis.
