چکیده
Despite many advantages of BrushLess DC motor, torque pulsation is one of the most important disadvantages of it. At first, an optimum primary design of BLDC motor is done using PSO algorithm. Then, other parameters for reducing the torque pulsation are considered by finite element method. It is shown that fractional slot structure has many advantages than conventional one. Both cogging and ripple torque have been reduced for fractional structure. In the next steps, other important torque pulsation parameters, such as magnet embrace, offset and skew are considered. Proper embrace, skew and offset are achieved for reducing torque pulsation by nonlinear finite-element analysis.
