An improved performance analysis of a shaded pole motor

摘要

In this paper a methodology for an improvedudperformance analysis of the shaded pole motorudis presented. They are used different approachesudto the computation of the motor characteristics. Byudusing them, a complex analysis of the single phaseudshaded-pole motor is presented. On the basis of theudresolving field theory, a circuit model of the motor isudderived. The FEM model of the motor is also developed.udBy using the Finite Element Method, a set ofudcalculations is carried out and the distribution of theudmagnetic flux density in the air gap is obtained. Theudshaded-pole motor under consideration is studiedudexperimentally, too. The obtained results, are mutuallyudcompared. A special emphasis is given to the investigationudof the shading portion of the pole and on itsudeffect on the motor performance characteristics.
