1. A steering motor control device for controlling a steering motor including a first winding and a second winding comprising:
a receiver configured to receive requested output information on an output requested for the steering motor;
a determiner configured to, if one of the first winding and the second winding is determined to fail, determine output distribution information based on the requested output information and reference output information, and determine normal winding control information for a normal winding and faulty winding control information for a failed winding among the first winding and the second winding based on the output distribution information; and
a controller configured to control an operation of the normal winding based on the normal winding control information and control an operation of the failed winding based on the faulty winding control information,
wherein the output distribution information comprises first output section information regarding a first output section of the steering motor and second output section information regarding a second output section of the steering motor,
wherein the determiner divides the an output section of the steering motor into the first output section and the second output section based on the requested output information and the reference output information, and determine the first output section information and the second output section information including information about section distribution winding and section size for each of the first output section and the second output section, and
wherein, if the requested output information exceeds the reference output information, the determiner determines that the section distribution winding of the first output section information is the normal winding and determines the section size of the first output section information to a size of the reference output information, and determines that the section distribution winding of the second output section information is the failed winding and determines the section size of the second output section information as a size obtained by subtracting the reference output information from the requested output information.
