Claim 0:
1. An electric power steering device comprising:
a steering motor including a first winding and a second winding, each of which receives applied three-phase power;
a first control unit configured to control power supplied to the first winding; and
a second control unit configured to control power supplied to the second winding,
wherein, when an open-circuit failure occurs in one of one phase of the first winding and one phase of the second winding, among the first control unit and the second control unit, the control unit that controls the winding having the one phase, in which the open-circuit failure has occurred, performs torque compensation control increasing a maximum torque in a section, in which torque is generated, in the winding in which the one-phase open-circuit failure has occurred to additionally output compensation torque.
