This paper proposes a new analytical model of double star induction motor under bearing faults. Using combination of modified winding function and Fourier series approaches, inductances and mutual inductances of the motor are calculated analytically. In this work, one type of bearing faults has been analyzed: outer raceway. It has been shown that, the stator current spectrum contains other significant harmonic components than the well known characteristic frequencies of bearing faults. These harmonics can be located around the rotor slot harmonics (RSH).
