<P>PROBLEM TO BE SOLVED: To detect abnormality of a motor control device with a simple configuration. <P>SOLUTION: The motor control device includes: a first current sensor; a second current sensor; an angle sensor for obtaining a rotation angle of a three-phase motor; and a motor control part. AC current values of respective phases except one among three-phase AC currents supplied to stator coils of the respective phases of the three-phase motor are detected by the first current sensor and the second current sensor, respectively. An angle sensor obtains the rotation angle of a rotor of the three-phase motor. Based on the rotation angle obtained by the angle sensor, the motor control part determines the abnormality of the respective current sensors by determining whether the current values obtained by the respective current sensors are different in a predetermined electric angle from a command value from the motor control part. <P>COPYRIGHT: (C)2009,JPO&INPIT |
