摘要：
The radial electromagnetic forces in induction motors play an important role in the production of audible noise and vibrations. The magnetic flux pulsations at the iron surfaces produce these radial-forces, which act on the stator and rotor structures. An analysis for the calculation of the various field-harmonics and radial-forces in squirrel-cage induction motors, is presented in this paper. To verify the validity of the analysis, a squirrel-cage induction motor is analyzed. Theoretical and experimental results are presented with a view to determine the actual role played by the air-gap harmonic-fields on the radial-forces. Also, the effects of loading on the radial-forces and the ensuing vibrations are closely examined.
