Abstract

The control method includes obtaining an assumed angle and an actual angle of each of the plurality of rotation angle detecting members, determining a first rotation angle detecting member, the assumed angle and the actual angle of which differ from each other, determining a second rotation angle detecting member having the actual angle closest to the assumed angle of the first rotation angle detecting member, resetting the given count value of the second rotation angle detecting member to a new count value of the first rotation angle detecting member, changing the actual angle of the first rotation angle detecting member via the new count value of the first rotation angle detecting member to reduce an angular error between the assumed angle and the actual angle of the first rotation angle detecting member.
