The paper presents a metaphysical model of the rotor dynamics of an asynchronous motor spindle that accounts for the effect of magnetic eccentricity. The study proposes a new approach to modeling unbalanced magnetic pull (UMP) based on a variable mutual inductance of the magnetizing circuit instead of the classical Maxwell stress tensor method. Analytical dependences between the air-gap eccentricity, magnetizing inductance, and UMP components are derived, and a modified Simscape/Simulink model of the asynchronous machine is implemented to simulate these relationships. The simulation results demonstrate the influence of magnetic eccentricity on the electromagnetic torque, stator current spectrum, and rotor speed. The proposed model provides a practical tool for diagnosing eccentricity-related faults and predicting vibration behavior in motor spindles
