Magnetic Field Analysis Using All Unkown Secondary Current Quantities in Shaded-Pole Type Induction Motor.

A New Restructured Shaded Pole Induction Motor- 3D Finite Element Analysis and Experimental Verification

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 analysi...

Comparison of 2D and 3D magnetic field analysis of single-phase shaded pole induction motors

There has always been doubt on the accuracy of 2D analysis of small electric machines. To investigate the validity of this doubt, in this present work a small uni-coil shaded-pole induction motor is analyzed in 2D and 3D and the results are compared. In order to maintain the paper size as compact, the analysis is limited to the air-gap flux density distribution, variation of the main winding in...

Analysis of Shaded Pole Induction Motors Considering Asymmetrical Flux Distribution and Saturation Effects

Several methods are available for performance prediction of single phase shaded pole induction motors. A simple model, in conjunction with a more complicated and accurate model, which considers the asymmetrical windings and core loss, is used to compare the prediction methods against experimental results. Saturation is incorporated in the model. Fundamental and harmonic flux density wave distri...
