The characteristic calculation of reluctance Brushless Doubly-fed Machine (RBDFM) using tooth flux method

The calculation method of the no-load and on-load characteristic of reluctance brushless doubly-fed machine (RBDFM )is proposed based on tooth flux calculation. The tooth flux of RBDFM can be obtained by infinite-element calculation, and then the voltage value and waveform can be accurately calculated by the tooth flux value. The effects of the magnetic circuit geometry, saliency, saturation, winding layouts, and slotting are included. The characteristic and voltage waveform of RBDFM has been analyzed and improving method has been discussed.
