摘要： In an electric motor control apparatus, an electric motor driving unit includes: a current detection unit configured to detect a current flowing through a current detection place in the electric motor driving unit. A control unit includes a current calculation unit configured to calculate a current value of a current flowing through an electric motor from an offset correction value obtained based on a first detection value detected at a time when a current flows through the current detection place and a second detection value detected at a time when a current does not flow through the current detection place. The offset correction value includes: a first offset correction value stored in nonvolatile memory of the control unit at a time of assembling the electric motor control apparatus; and a second offset correction value computed by the control unit while the electric motor is driven.
