Discussion of "Analysis of a new variable-speed singly salient reluctance motor utilizing only two transistor switches" by L. Xu et al

Abstract

C. Patak maintains that the motor analyzed by L. Xu et al. in the above-titled paper (see ibid., vol.26, no.2, p.229-36 (1990)) cannot operate as specified by the authors. R.M. Davis, in a separate discussion points out that the above-titled paper is based on earlier work by L. Xu and T.A. Lipo (1987, 1988) that had prompted him to publish a paper in which he reached a completely opposite conclusion, and that L. Xu et al. have neither noted nor referenced his work. In reply, L. Xu et al. point out that Patak has been misled by Fig. 4 of their paper and provide clarification. They also explain why they did not consider Davis's paper and rebut his arguments. They also note that the captions for Figs. 14 and 15 of their paper should be reversed. >
