Shaded pole induction motors, despite the simplicity and low cost, are difficult to analyze particularly in the equivalent circuit methods, due to the asymmetric structure, saturation, harmonics, inaccurate estimation of leakage inductances and skew. Hence, 3D numerical methods could be very useful in the design and optimization stage. This paper presents the 3D transient finite element analysis (3DTFEM) of a 1/60HP, 2-pole prototyped, restructured shaded pole induction motor that has been designed and optimized using genetic algorithm technique. Experimental test has been carried out by a hysteresis brake dynamometer to determine the motor performance. Detailed comparisons among 2D, and 3D finite-element analysis, and experimental results are presented, which confirm the potentials of the new restructured shaded pole motor to achieve lower cost and higher efficiency objectives than the previous designs.
