The brushless doubly fed induction machine (DFIM), without brushes and slip rings, is regarded as an attractive alternative to the conventional DFIM in terms of reliability. This paper presents a sensorless field-oriented control strategy for the brushless-DFIM, which further increases its attractiveness as a drive system. With the use of a straightforward and alternative time-dynamic brushless-DFIM...
Although the brushless Doubly-Fed Induction Machine (DFIM) has great potential as generator system in large-scale wind turbines, its complexity has so far retained a commercial breakthrough. This paper contributes by combining brushless DFIM Finite Element (FE) modelling with multi-objective optimization. A static brushless DFIM FE model is applied with the NSGA-II multi-objective optimization algorithm...
