A motor control apparatus includes: multiple motor drive circuits that drive at least one motor; and multiple microcomputers that are operated by a microcomputer power source and include a drive signal generator that generates a motor drive signal. The microcomputers include at least one microcomputer including a stop determiner that determines that operation of an own microcomputer is about to be stopped and transmits information as a stop determination signal. A microcomputer having received the stop determination signal from at least one different microcomputer actually stops operation of an own microcomputer.
