<P>PROBLEM TO BE SOLVED: To obtain rotor rotation angles with less errors, while reducing a load on an adjustment person, concerning a device for detecting a rotor rotation angle by using a resolver. <P>SOLUTION: An angle measurement value acquisition part 210 acquires the rotation angle measurement values of a motor shaft. An error calculation part 220 calculates errors included in each one of multiple rotation angle measurement values. A frequency component acquisition part 230 acquires the phase and amplitude of each frequency component of the errors on the basis of the multiple errors. Thus, an error frequency component acquisition device 121 automatically calculates the phase and amplitude of each frequency component of the errors included in the rotation angle measurement values and performs correction with respect to the rotation angle measurement values with the use of the phase and amplitude. Consequently, rotor rotation angles with less errors are obtained while reducing a load on an adjustment person. <P>COPYRIGHT: (C)2013,JPO&INPIT |
