The invention relates to an electromagnetic shielding and insulating structure of an ultrasonic motor stator elastomer assembly, which adopts an indirect insulating isolation mode to insulate the stator elastomer assembly, and specifically comprises a shell assembly, a pre-pressure adjusting gasket, a rotor assembly and a stator seat assembly which are coaxially arranged in sequence from top to bottom, the stator base assembly comprises a stator elastomer assembly, a stator support, an insulating spacer and a stator base which are coaxially arranged in sequence from top to bottom. A motor ground wire and a shielding ground wire are respectively led out from the stator seat assembly, the shielding ground wire is led out from the stator seat, the motor ground wire and the shielding ground wire are mutually independent and are not conducted, and an A-phase lead-out wire and a B-phase lead-out wire on the stator elastomer assembly are twisted in pairs, then twisted in pairs with the motor ground wire and wrapped
