An exact 2-dimensional analytical method for calculating the magnetic field distribution in a Flux Concentration Permanent Magnet Machines (FCPMM) with sector magnets is developed and validated. The ability of the model to determine the performances of rectangular magnets FCPMM is then analyzed. A parametric study showed that the analytical model can predict the torque with a reasonable precision. Hence, this model can usefully be used for optimization purposes where savings in computation time are needed.
