Brushless DC motor torque improvement with mgnetic material stator core

In transportation, BLDC motors are required to have high torque. This BLDC electric motor is designed to drive an electric car. Increased torque can be done in many ways one of which is the selection of the stator material. Effect on the generated torque can be studied by replacing its stator materials. Design was begun with determining the electrical circuit and the coil for the excitation power. Electric motors which was simulated in this paper was a 3-phase BLDC motor. Voltage and current data were analyzed to study the motor performance when different core materials used. It can be concluded that applying ferrite materials stator core reduced core loss, while using ferrite core on the stator slots produces higher voltages and lower currents. Based on the magnitude of the torque produced by the electric motors, ferrite materials was more suitable to be used as slots of the stator core for better motor.
