Abstract

An analytical expression for the cage rotor magnetomotive force (MMF) is derived using the winding function approach. This approach enables the analysis of stator current spectra in the cage rotor induction machine. It is demonstrated that in stator current spectra one can observe only harmonic components at high frequencies, known as the rotor slot harmonics. The position of these components in stator current spectra depends on the number of rotor bars, number of poles of the induction machine, and slip (i.e., on the actual speed of rotor).
