Abstract

A problem is to provide a motor control apparatus which can smoothly control rotations inexpensively and with a large capacity without increasing the number of parts even if the work to be driven and controlled increases. In a control portion 28, a brush pair (8P and 8N or 9P and 9N) for generating a rotationally driving force in each first, second motor 11, 12 is selected by a relay changeover portion 19b of an engine control system 19, and a relay unit 17, 27 is changed over. Here, a control current from the relay unit 17 is temporarily suspended, and the other relay unit 27 is changed over to a current-conductive state. The control portion 28 is also connected to a first drive portion 31 and a second driver portion 32 to supply first and second control signals b1 and b2 thereto respectively. The first and second control signals b1 and b2 serves as synchronization signals from a PWM carrier generating portion 40 to contribute to PWM driving control of the first and second motors 11 and 12 together with rectangular waves k having the same cycle and the same wavelength.
