An anomaly detector determines whether or not the absolute value of a detected first electric current value Ix_hp and/or the absolute values of second electric current values Ix_Ip exceed a first threshold I1 that is set corresponding to the limit value (+-Ilim) of the electric current detection. The anomaly detector also determines whether or not the absolute value of a phase current value Ix thus detected is less than a second threshold I2 that is set corresponding to "0 (zero)." In the case of a phase that fulfills both of these two determination conditions, a determination is made that a sensor anomaly (a stiction anomaly) has occurred in the relevant phase.
