In this study, mathematical modeling of outer rotor brushless direct current motor (BLCD) is performed. Brushless direct current motor is highly preferred in industrial applications when compared the other motor types with considering advantages and disadvantages. Producing higher torque with smaller dimensions, being easily controllable and developing high efficiency electronic materials can be given such an example of these advantages. In this study, an outer rotor brushless DC motor which was used in the laboratory is modeled. This motor hasn’t currently information parameters. For this reason, first of all, the metric measurements, phase winding orders are obtained for the motor parameters.  With the motor parameters that we have, the motor was created and analyzed in Maxwell program environment. And then the parameters (torque constant, back EMF constant, phase resistance, etc.) were obtained required for the simulation. Mathematical model was completed with the obtained parameters in Matlab / Simulink environment. So, Torque characteristics, motor speed and trapezoidal back-EMF were determined. The motor currents matched with the Maxwell and Matlab / Simulink programs. So the accuracy of the simulation modeling has been confirmed.
