Abstract :
In this paper, a novel integral-force technique to calculate the developed torque of an axial-field permanent magnet brushless DC (PM BLDC) motor using minimum requirement of 2D FE analyses is presented. In an axial-flux motor, 2D modeling is not sufficient and it necessitates 3D FE modeling. Using the new method explained in this paper, the designer can find the performance of the motor using 2D FE modeling itself. The design data of a conventionally designed motor have been considered in 2D and 3D FE models.
