Mathematical models of three-phase asynchronous motors supplied by mains

摘要

Mathematical model of three-phase asynchronous motors supplied by the mains according to four the most used circuits have been developed. The models are written in (α-β) coordinates and then are transformed in to a basis model by using a method of symmetrical components. Expressions of the parameters and voltages for a transmission to the basis model are obtained. The results of calculating starting operating conditions of the asynchronous motor 4AA56A4Y3 rated 120W supplied by the mains are given.
