1. An electric machine system, comprising:
an electric machine comprising a stator that comprises coils, and a rotator that comprises a magnet and is rotatable with respect to the stator;
an electric power converter that inputs and outputs electric power with respect to the coils of the electric machine; and
at least one processor configured to:
correct a phase of a signal so that a magnitude of a correction reference approaches an extreme value, wherein the signal is for operating the electric power converter and the phase of the signal determines an input timing or an output timing of the electric power with respect to the coils of the electric machine, and
output the signal to the electric power converter.
