Design and torque capability of a ducted rotor brushless doubly fed reluctance machine

摘要

This study discusses the design strategy and response analysis of the brushless doubly fed reluctance machine (BDFRM) with an aim of commercially feasible implementation with satisfactory performance. In this regard, basic operation theory is reviewed, and a control strategy is proposed to maximise the motor torque capability. A BDFRM design is proposed and simulated for investigation. Subsequently, a prototype machine is built and tested. Predicted simulation torque data is compared with the actual machine data to evaluate the design approach.
