Design Methodology and Considerations to Energy Efficient Switched Reluctance Motor for Ceiling Fan Application

In this paper, a robust design methodology is presented for a switched reluctance motor (SRM) for ceiling fan application. In the first section, 6/8, 8/6, 8/10, and 12/16 pole configurations of SR motor are designed in Maxwell 2D software for the same dimensions and magnetomotive force (MMF) excitation for a ceiling fan. A comparative analysis is done to figure out the effect of phases, rotor poles, and multiplicity. Further, a new design of a 12/16 pole SR motor is proposed for ceiling fan application. The static and dynamic analyses of the motor are done to find out the motor performance. A look-up table-based model of 12/16 pole SR motor in MAT LAB Simulink platform is simulated. Mechanical transient performance is also investigated using the Maxwell based external circuit connection. The look-up table-based model and external circuit connection simulation model with mechanical loading have good agreement with each other.
