Znaczenie użycia koncentratora magnetycznego w obwodzie magnetycznym silnika synchronicznego ze stałymi magnesami wewnątrz wirnika

In the paper the results of the simulation and analysis of the interior-permanent magnet synchronous motor have been presented. In the research FEM method was applied. Magnetic concentrator, made of high material permeance with saturation up to 2,35 T, was used to form the magnetic flux. All simulations for computing torque, flux density and cogging torque were calculated in Flux 2D and FEMM commercial programmes. The differences between static torque of the rotor with and without magnetic concentrator were presented in the paper. The numerical simulations showed the influence of the magnetic concentrator on the torque and the cogging torque in the interior permanent magnet synchronous motor.
