PROBLEM TO BE SOLVED: To provide an electric power steering device for driving and controlling a three-phase motor according to steering torque of a driver, configured to reduce torque ripple generated in the motor due to a difference in phase delay amount between current sensors of two-phase detection current.SOLUTION: A motor 30 is driven on the basis of a target current It set by a target current setting section 68, and corrected detection currents Iu, Ivand Iwacquired by correcting detection currents Iu', Iv' detected by current sensors 56, 57 by a detection current phase correction section 62. |
