Abstract :
The present paper attempts to investigate the effect of space distribution of rotor bars in squirrel cage induction machine on the generation of the rotor slot harmonics (RSH). An analytical expression of the stator current describing the necessary relationship between rotor bar and pole pairs numbers required for the presence of RSH has been developed. The proposed expression is based on the linkage inductance expression derived using the winding function approach (WFA) and its decomposition into Fourier series. An important issue in such effort is to predict RSH in healthy machine as well as in machine with broken rotor bars
