Abstract :
This paper presents a novel method in which eddy current losses in a solid rotor direct torque controlled synchronous machine are found by utilizing a combination of analytical and FEM (finite element method) simulations. The method is presented along with the results obtained. The article also briefly presents a new method in which 3D (three dimensional) current flows can be modelled using a 2D (two dimensional) FEM model.
