Special attention is paid to slotting effect. The PM machine is integrated in flywheel and used for small-scale ship application. Analytical model and automated nonlinear transient finite-element-model (FEM) including rotor motion are developed. A new hybrid model combining analytical model and static FEM model with single rotor position for the design of PM machines is developed. The hybrid model is an improvement of the analytical model on calculation accuracy and of the transient FEM on calculation time. The electromagnetic FEM model and circuit thermal model are coupled to form a multiphysics model for the design of PM machines taking temperature constraints into account. New insights into the influence of slotting effect on the performance of PM machines in the range of small slot opening are provided. Optimizing design parameters of the PM machine is investigated. Iron loss modeling and analysis are also addressed. The most suitable configuration of the PM machine for the application is found and described. The developed models are experimentally validated.
