N2 - The proposed hybrid method combines Computationally Efficient-Finite Element Analysis (CE-FEA) with a new analytical formulation for eddy-current losses in the permanent magnets (PMs) of sine-wave current regulated brushless synchronous motors. The CE-FEA only employs a reduced set of magnetostatic solutions yielding substantial reductions in the computational time as compared with conventional FEA. The 3D end effects and the effect of PWM switching harmonics are incorporated in the analytical calculations. The algorithms are applied to two fractional-slot concentrated-winding interior permanent magnet motors with different circumferential and axial PM block segmentation arrangements. The method is validated against 2D and 3D Time Stepping (TS) FEA.
