“…As the heart of the majority of kitchen appliances, electrical motors have a determinative role in the efficiency and total performance of the so-called devices. Thus, extensive studies have been carried out for designing compact, high performance, high power to weight ratio and low-maintenance electrical machines [1][2][3][4]. Through years of evolution of the electrical machines employed in home appliances, the universal motor is one of the very first machine that has been widely used.…”

Electrical machines are widely used in home appliances, the performance of which is mostly related to the quality function of the electrical machines. What has been used so far in home appliances brought with themselves a wide assortment of advantages and disadvantages. With the aim to overcome the drawbacks of the previously implemented electrical motors in washing machines, a new configuration of flux switching permanent magnet motor (FSPM) with the segmented outer rotor (SOR-FSPM) is proposed benefitting from a direct driven drum. To reduce the cogging torque as well as torque ripple and to improve the total harmonic distortion, cutting the stator in a way to lower overlapping between the rotor and stator pole, inserting notches into the poles of the rotor to modify the air gap between the stator teeth and the rotor segments are proposed. The Taguchi method and sensitivity analysis are further applied to find the best combination set of changes in such a way to smoothen the chart showing reluctance between stator and rotor and fix the zero-point crossing of the flux linkages in different rotor positions. Finally, the proposed SOR-FSPM is prototyped, and experimental results along with the finite element method results are discussed and compared in order to verify the design process.
