In this paper a methodology for an improved performance analysis of a shaded pole motor is presented. They are used different approaches to the computation of the motor characteristics. On the basis of the resolving field theory, a circuit model of the motor is derived. The FEM model of the motor is also developed. By using the Finite Element Method, a set of calculations is carried out and the distribution of the magnetic flux density in the air gap is obtained. A deepened analysis of influence of the shading portion of the pole is presented too. The shaded-pole motor is also studied experimentally. The obtained results, are mutually compared. They show a reasonable agreement. |
