Abstract
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 of turning mechanisms 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 and two inverters for separately driving the three-phase windings.
