Abstract: Motor control device includes a controller controlling a motor (a calculator controller and an electric current controller), and a detector (an electric current loop) detecting an electric current of the motor and returning the detected electric current to the controller. The electric current loop includes a first detection system, a second detection system, and an electric current calculator which sums output signals from each system. Each detection system includes a sensor detecting the electric current of the motor, and a weight adjuster outputting to the electric current calculator, a detection electric current value from each sensor multiplied by a weight coefficient.
