Abstract:
The brushless motor includes a first permanent magnet magnetized in a direction perpendicular to the drive direction, and a electromagnetic coil wound around an axis parallel to the drive direction. The drive control circuit supplies a drive current in a given first electric current direction to the electromagnetic coil without changing the electric current direction to operate the brushless motor in the drive direction.
