Finite Element Analysis of the Tolerance of the Multi-Phase Induction Motors regarding Stator Winding Failures

The paper analyses the tolerance of the three-phase, five-phase, seven-phase and nine-phase squirrel-cage induction motors regarding stator winding failures by using finite element models step by step in time domain. Failures that appear during the full load steady state motor operation and failures existing before the motor start-up are considered.
