摘要

This article presents a technique for vector control of star-connected 3-phase induction motor drives with an open-phase fault (faulty 3-phase induction motor) based on the rotor flux field-oriented control method. In this method, two appropriate transformation matrices are applied to the equations of faulty induction machine. It is shown that the structure of the derived faulty induction machine equations is similar to the healthy 3-phase induction motor equations; make it possible to control a faulty machine with some modifications in the conventional controller. Hence, a modified rotor flux field-oriented controller that capable to control a star-connected 3-phase induction motor under open-phase fault is proposed. The performance of the proposed method is verified through simulations and experiments ona 1.5kW star-connected 3-phase induction motor drive. The comparative results obtained from the simulations and experiments confirm the ability of the proposed control method in vector control of 3-phase induction motor during open-phase fault.
