Design and Development of Energy Efficient Single Phase Induction Motor For Ceiling Fan Using Taguchi's Orthogonal Arrays

The conventional single phase induction motor (SPIM)-based ceiling fans are difficult to design using the analytical procedure because of inherent nonlinearities in the electromagnetic construction. The high skewing of rotor bars to eliminate low-order harmonics makes the analytical solution based on a 2D magnetic circuit, which is quite inaccurate. This article deals with the systematic design and experimental validation of the energy-energy efficient SPIM for ceiling fan application. A systematic approach starting from the existing SPIM motor is presented for improvement in the efficiency of the motor using 2D finite element analysis (FEA). The process involves the design validation of the existing ceiling fan motor followed by a set of experiments (2D multislice time-stepping transient FEA) to obtain the energy-efficient motor. Taguchi's orthogonal arrays are used for the improvement in the performance of the motor. Finally, the achieved optimal design is developed and tested for the improvement in the performance.
