Abstract
when analyzing induction machines, considering their AC excitation, the air gap magnetic field is always a time-varying quantity. In such case, the non-linear time harmonic analysis by using FEM (Finite Element Method) should be applied. in the paper, the results of FEA (Finite Element Analysis) of a shaded-pole micromotor, as a challenging object for investigation, are presented. An accurate calculation of the air-gap flux linkage and magnetic co-energy is performed and the characteristics are presented on diagrams. The electromagnetic static torque is calculated at different currents, and its characteristics are derived and presented, as well. The numerically calculated values of static electromagnetic torque are compared with the measured ones, proving that applied FEA as quite accurate. In addition, the comparison with the analytically obtained value are presented, too. Dynamic behaviour of the motor is analysed on the basis of transient characteristics.
