The paper presents an attempt to explain physical meaning of self-induction and mutual induction processes on the basis of vector potential realization as “an electricity current equivalent”.

This paper introduces a technique for deter- mination of electromagnetic parameters of a squir- rel-cage rotor winding in an induction motor. The technique treats a squirrel cage rotor winding as an equivalent single-turn winding ( 120 =w , in publi- cations on the subject 5,020 =w ) with the number of phases equal to the number of the stator winding phases ( 1020 mm = , in publications 220 Zm = ).
