Motor driving device, motor system equipped with the motor driving device, imaging apparatus, and motor driving method

摘要

Problem to be solved: to provide a motor driving device capable of generating a driving waveform with a small reaction delay and maintaining a smooth waveform even when the phase difference command is changed.The motor driving apparatus according to the present invention comprises a rotation position detecting means 104 for detecting the rotational position of the rotor, and a driving waveform generating means 110 for generating a driving waveform to the motor based on the detected rotational position.Drive waveform generating meansThe phase difference setting means 306 for setting the phase difference between the rotational position and the driving waveform isIf the phase difference set in the phase difference setting means is changedA change time setting means 307 for setting a change time which is the time from changing the phase difference to a phase difference after the change from the phase change to the changed phase difference, andA phase determining means 303 for determining the phase of the drive waveform based on the phase difference before and after the phase change and the change time, and.Diagram
