Leakage Field Changes of an Induction Motor as Indication of Nonsymmetric Supply

An analysis of harmonics of leakage fields which appear in the vicinity of the motor at its symmetric and nonsymmetric supply is presented. The wave at the frequency (2 -s)·f 1 , which appears in the second case, may be utilized to protect the motor against single-phase operation.
