Influence of bearing units faults on distribution of magnetic induction in air-gap is considered on the basis of mathematical model of three-phase induction electric motor. The pictures of magnetic field lines distribution in radial and magnetic induction in longitudinal directions are given. Inhomogeneity of magnetic induction in the air-gap of motor results in appearance of highest harmonics in a consumable current and change of its spectral composition.
