A Simple Four-Phase Switched Reluctance Motor Drive for Ceiling Fan Applications

A simple four-phase switched reluctance motor (SRM) drive for a ceiling fan is presented in this paper. Here, an asymmetric bridge converter preferred due to its independent phase control and design. The proposed based SRM has no speed current feedback loops, thereby eliminating the use of sensors complex computational logic. Position sensing carried-out using hall-effect drive. Analytical simulation studies are on results presented. To verify efficacy prototype fabricated. Experimental show that low ripple acoustic noise as required applications.
