Abstract :
In this paper, a new model of 9-phase BLDC motor drive is studied and the model will be implemented using Matlab/Simulink software. The motor has been simulated through dynamic modeling and using the switching functions concept. In addition, in order to create constant torque and take advantage of the maximum torque capacity of motor, hysteresis current control method is used in the internal loop of speed and torque control system. According to the simulation results, a 9-phase BLDC motor has high torque capacity and low torque ripple. Thus, it is appropriate to use this model of BLDC motor in sensitive and high performance applications.
