Calculation of Unbalanced Magnetic Pull in Cage Induction Machines
… is not concentric with the stator then an electromagnetic force is generated in a direction that will increase the eccentricity. This is called unbalanced magnetic pull (UMP). The first part of the work presented in this dissertation develops theoretical models which allow the calculation of the …

The influence of unbalanced magnetic pull on the reliability of induction motors
This thesis is a study of the influence of unbalanced magnetic pull (~.m.p.) and associated phenomena on the reliability of induction motors. The work arose from investigations into the premature failure or malfunction of several large and important 6600 volt induction motors whilst in service. …

Analysis of the Dynamic Interferences Between the Stator and Rotor of a Refrigeration Compressor Motor
… phenomenon causing the rotor displacement was unbalanced magnetic pull. This phenomenon occurs in the air gap of rotating electric machines due to eccentricity in the air gap. The model was then subjected to simultaneous harmonic force inputs with magnitudes of unity on the rotor and stator …
