摘要：
An apparatus and method for recognizing a rotor position, and an electric power steering system using the same wherein resolution in rotor position recognition can be improved by software by adding one or more increment values, which is proportional to the rotation speed of a rotor, in an interval where the counted number of increment pulses of a pulse generator is not changed in sampling the counted number of increment pulses of the pulse generator so as to recognize a rotor position of a motor.
