Abstract
The motor control device includes plural motor current blocking units that, in blocking operation, individually block energization between plural motor driving circuits and multi-phase motor windings of a multi-phase electric motor and an abnormality detecting unit that detects a short-circuit failure of the motor current blocking units. The abnormality detecting unit causes one or more motor current blocking units of the plural motor current blocking units to perform a blocking operation during energization between the plural motor driving circuits and the multi-phase electric motor, and, during the blocking operation, detects a short-circuit failure of the motor current blocking units caused to perform the blocking operation based on current values of currents flowing to the plural motor driving circuits.
