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.
This paper describes two power converter variable frequency operation of the Brushless Doubly Fed Reluctance Machine (BDFRM) with a ducted rotor and distributed stator windings.. Basic background and control theories are discussed and an example design of the machine is presented for investigation. Predicted and simulated torque and power responses data is included to investigate the effectiveness of the two converter operation. A simple control approach to maximize the capability of a given design is presented.
