Abstract

PURPOSE:To construct a speed controller having less number of parts inexpensively with high reliability by controlling the speed of more than two motors simultaneously commonly with a controller. CONSTITUTION:A command value switching unit 2 switches a speed command value to the driving circuit 3 of a motor M1 and a driving circuit 3' of a motor M2 with a switching signal C1. The driving circuits 3, 3' are composed of latch circuits for latching the speed command value via latch signals L1, L2 from a controller 1 and a power amplifier for amplifying a signal sufficient to drive the motors M1, M2. Start-stop command and speed ratio signal of the motors M1, M2 are inputted to the controller 1.
