Abstract

Brushless DC (BLDC) motors offer a significant advantage in reliability over traditional DC motors due to the absence of mechanical brushes. The operation of BLDC motors relies on electronic switching, typically implemented using a six-pulse inverter. One effective control strategy is Field Oriented Control (FOC), which regulates the motor by independently controlling the d-axis (Id) and q-axis (Iq) currents. This method allows precise torque control similar to that of conventional DC motors. Additionally, by independently managing Id and Iq, This study explores the application of the FOC method to a 120 kW BLDC motor. Simulation results indicate that higher torque inputs lead to faster motor response in reaching nominal rotational speed, while lower speed reference values result in a longer transient period. The BLDC motor’s speed is effectively managed through a closed-loop speed control system. However, the presence of high torque ripple is noted, which is attributed to challenges in tuning the PI controllers, the high load condition of 100 Nm, and the influence of the trapezoidal nature of the motor's back-EMF.
