Abstract: In a MG control device, a standard voltage calculation part calculates a d axis standard voltage and a q axis standard voltage in a standard state in which no demagnetization occurs in permanent magnets of a MG. A magnetic flux change amount estimation value calculation part calculates a basic magnetic flux change amount estimation value based on a deviation of a specific value from the q-axis standard voltage. This specific value is obtained by multiplying q axis real voltage with a ratio of the d axis standard voltage and the d axis real voltage. A magnetic flux change amount estimation value correction part adjusts a magnetic flux change amount estimation value by correcting the basic magnetic flux change amount estimation value relatively to a detection threshold value based on characteristic change of the MG in a demagnetization state of the permanent magnets of the MG.
