A motor control device has a motor current detector for detecting current in windings to control the operation of a motor with a stator having three-phase windings. The motor control device includes a digital controller for outputting a PWM switching signal, a power converter for applying drive voltage to the windings using the PWM switching signal, a motor current detector for converting current flowing in the windings to analog voltage, a ӣ AD converter for converting the analog voltage to a 1-bit digital signal, an AD conversion decimating filter for generating a detected motor current value from the 1-bit digital signal, a clock generator for generating a clock for the ӣ AD converter and the AD conversion decimating filter, and a stop signal generator for generating a clock stop signal for stopping the clock of the clock generator for a predetermined period. The stop signal generator generates the clock stop signal with a predetermined pulse width based on a timing of the PWM switching signal, and the clock generator stops the clock for a period of the predetermined pulse width, using the clock stop signal.
