Abstract
A scale pulse signal is produced whenever a revolution sensor detects a unit revolution angle formed an angle between cogs of poles. A time interval between the scale pulse signal is affected by an error in the formed angle. The time interval between the scale pulse signals can be corrected by using a correction coefficient detrmined by an actual value of the unit revolution angle detected by the revolution sensor and by a design value of the unit revolution angle, so that the time interval corresponds to the design value of the unit revolution angle.
