An electric power steering apparatus having independent turning mechanisms for respective four wheels of a vehicle, has a problem in that, when a turning motor fails, a turning mechanism for a corresponding wheel stops functioning, resulting in reduction in the maneuverability and the stability of the vehicle. Turning motors 13a, 13b, 18a, and 18b of turning mechanisms 3a, 3b, 4a, and 4b independently disposed for respective four wheels of a vehicle, each have a redundant configuration. Specifically, each turning motor is configured as three-phase duplexing motors having two three-phase windings 19a and 19b and two inverters 22a and 22b for separately driving the three-phase windings.
