Doubly Salient Ferrite rotor PM single phase SM motor: FEM based optimal design and analysis
2021
A new asymmetric airgap single-phase motor PM topology for small power (below 100W) applications is introduced and investigated in this paper. Its main feature is the placement of the PMs in the rotor in a V-shape arrangement for flux concentration. The particularities of this new topology are investigated and a FEA based multi-objective optimal design methodology is built and used for optimizing the material cost, efficiency and starting torque. The optimal design results are validated via dynamic simulation.
