Design of a doubly fed reluctance motor for adjustable-speed drives

Abstract

A methodology for the steady-state performance analysis and design of the doubly fed reluctance motor (DFRM) is presented in this paper. Emphasis is placed on the linear model of the DFRM, but magnetic nonlinearities are also characterized. A prototype 2 hp DFRM is designed and built in comparison with an induction motor. Performance of the prototype 2 hp DFRM motor is analyzed thoroughly and is supported by actual measurements, wherever available.
