Outline of Final Research Achievements

The problem that the stepping motor becomes unstable has been known as a resonance phenomenon for a long time. In response to such a problem, elucidation of instability caused by a combination of elucidation of an unstable phenomenon from a drive unit and a particularly problematic mechanical system Was carried out.
In the 2-phase hybrid type, we developed a driver that has the function of observing the state by integrating the instantaneous value of the drive current and voltage and the phase angle to the actual rotation angle by the command pulse driven by the open loop. From the position detection by the encoder and the output of the driver, the drive state in the middle speed range can be examined in detail. In parallel, we developed a method to confirm the theoretical cause of vibration generation by developing a simulation program that combines the driving state with electromechanical. It was.
