PURPOSE: To accurately control a motor even when either one of a first or a second resolution speed sensor gets out of order. CONSTITUTION: A motor control device 10 is provided with an accelerator 14 for outputting an acceleration signal SA as the target value of the revolution speed of a motor 12, revolution speed sensors 161, 162 for detecting the revolution speed of the motor 12 and a microcomputer 20 for controlling the motor 12 through a driving circuit 18 on the basis of revolution speed signalsϕ1 ,ϕ2 and the acceleration signal SA. The microcomputer 20 controls the motor 12 on the basis of the higher one of the revolution speed signalsϕ1 ,ϕ2 . |
