An approach is proposed for measuring the rotor eccentricity of an induction motor by broadband frequency modulation of a sweep frequency generator. The functional structure of the device is developed on the basis of the nonuniform reluctance of the motor’s magnetic core associated with the nonuniform air gap. The compression time and twist angles of the shaft are determined for different rotor eccentricity.
