Abstract
An increase in noise can be suppressed. A motor control device includes N inverters configured to control N motors connected via power cables based on PWM signals, respectively, and a phase controller configured to determine phases of N carrier signals to be used for generating PWM signals to be supplied to the N inverters so that a sum of N vectors represented by noise amounts related to the respective N motors becomes zero.
