Rotor Oscillation Damping of a Stepping Motor Using PWM-Type Switching Sequence

概要

論文の詳細を見る
In this work, the authors suggest the method for damping of natural oscillation of a stepping motor, which only requires adjustment of switching sequence. The robustness against variation of the load inertia is taken into consideration in this method. The switching sequence is constructed being based on the waveform which do not contain the frequency component in the region where the natural frequency of the motor, varies with change of load inertia, can be exist. Pulse width modulation is used to transform the waveform to the switching sequence. The effectiveness of this method is confirmed by the experiment.
