DETERMINATION OF EQUIVALENT SCHEMES OF DEEP-BAR INDUCTION MOTORS PARAMETERS USING EXPERIMENTAL DATA

This work is devoted to development of identification parameters methods of deep-bar induction motors from experimental data. The main feature of prepositional method is using of data registration of phase currents and voltages values, slip value in starting condition, and work conditions with difference load factor. Account of rotor current skin-effect for intermediate slip values is made by using of equivalent square slot hyperbolic dependences. The special active-inductive circuit similar to rotor circuit is marked out for accuracy increasing of dynamic conditions calculations.
