Low-frequency mechanical forces, electromagnetic forces of the medium frequency band, and high-frequency switching frequency current harmonics are three main sources of vibration for electric vehicle (EV) motors under multiple operating conditions (MOCs). These high-frequency vibration sources with large amplitudes are mainly concentrated around the switching frequency and its integral multiples (sideband vibration). The theoretical expression and frequency characteristics for the high-frequency electromagnetic force that produces sideband vibrations were presented in this article, and a new parameter $\bar {x}$ (the current harmonic amplitude average value) was designed to represent the harmonic level of the current supplied by the inverter in the sideband vibration band. Finite element simulations based on Simplorer-Maxwell-Vibration Harmonic Response and experiments under MOC verified the above theoretically derived characteristic-frequency band of high-frequency electromagnetic forces that generate sideband vibrations. To reduce sideband vibration, an optimized scheme combining active disturbance rejection control (ADRC) and random frequency space vector pulsewidth modulation (RFSVPWM) was proposed to further reduce the parameter $\bar {x}$ and sideband vibration compared to traditional PI, ADRC, and PI-RFSVPWM. Finally, the feasibility of this scheme for depression sideband vibration was verified by simulations under MOC.
