<p>PROBLEM TO BE SOLVED: To provide a configuration for detecting a rotor rotation position of a motor more properly, while preventing increase in physical size and cost of a device.SOLUTION: A motor and a resolver are configured so that a pole number ratio between the number of poles of a motor and the number of poles of a resolver is set so as not to periodically change an error of a resolver angleφfrom an R/D converter due to a leakage flux from the motor. The resolver angleφfrom the R/D converter 40 can be easily and properly corrected, to properly calculate an electric angleθe or the like of the motor 22.</p> |
