A control device and a control method for a rotary electric motor, and a rotary electric motor drive system capable of reliably suppressing vibration of the rotary electric motor are provided. A rotary electric motor is controlled by PWM at a predetermined carrier frequency, and in a case where a vibration frequency in a space zero-order eigenmode of the rotary electric motor and a frequency of a frequency component of electromagnetic exciting force that generates the eigenmode overlap with each other, a value of the carrier frequency is switched from a first value to a second value different from the first value.
