Abstract

An electric power steering apparatus using a brushless motor is disclosed. The electric power steering apparatus has a microcomputer for calculating a target current to the brushless motor on the basis of a torque signal outputted from a steering torque detecting part. The microcomputer has a table stored in ROM. The microcomputer calculates the angular position of the brushless motor by referring to the table on the basis of a signal outputted by a resolver.
