Modelowanie konstrukcji mikrosilnika ze zwojem zwartym na podstawie analizy polowej

The analysis of magnetic circuit of shaded pole induction motor (SPM), for basic micro - motor type 925 powered 3W, was conducted. The magnetic shunt as well as number and location of the compact laps are the influencing on electromagnetic parameters SPM elements, making up the auxiliary starting winding of motor. It the row of field calculations was executed from utilization the software OPERA 2d for different constructions of magnetic circuit of motor, and the different number of laps (thirteen the computational models). The simplest construction, and the simultaneously cheapest solution are then magnetic shunt is executed as prolongation of stator poles from one compact lap on pole. The realization of shunt made from the same electrotechnical sheet, what the whole core of motor is profitable technologically, however to reach hard near this the satisfactory electromagnetic parameters. The base of comparison of parameters row studied models establish the optimum solution of magnetic circuit of motor, the largest value of flux density in air gap and also the largest starting moment of motor was obtained.
