Document Type and Number:
Japanese Patent JP2022137360
Kind Code:
A
Abstract:
To suppress an increase in noise.SOLUTION: A motor control device includes N inverters that controls N motors connected via power cables on the basis of PWM signals, and a phase control unit that determines the phases of N carrier signals used to generate PWM signals to be supplied to the N inverters such that the sum of N vectors represented by the amount of noise respectively associated with the N motors is zero.SELECTED DRAWING: Figure 1
