Abstract: A motor control device that detects a motor current through ΔΣ AD conversion includes a stop signal generator and a stop signal controller. When a difference between a maximum value and a minimum value of three phase voltage command values to be applied to a motor is smaller than or equal to a predetermined threshold, a stop signal that causes the ΔΣ AD conversion to stop is output with a delay by the time corresponding to a delay in current detection while a leakage current caused by on and off of a power conversion element is occurring.
