| dc.description.abstract | Brushless DC Motor (BLDCM) is broadly utilized for a few mechanical applications, given their high efficiency, high starting torque, low volume, high torque, and less electrical noise. Brushless DC (BLDC) motors are widely used these days due to their advantages over conventional DC motors. A Hall effect sensor generates a signal sent to a three-phase power semiconductor bridge to control BLDC. The motor can also be regulated to achieve the desired level of performance by using an open loop and closed-loop control system. This thesis focuses on the speed control technique of BLDC motors using MATLAB/ Simulink. It presents the design, development, and simulation of open-loop and closed-loop system operation to power an 8-pole and three-phase BLDC motor. The software used in this research is MATLAB SIMULINK, which provides simulation for the data in this thesis. MATLAB will implement a motor application that uses the Hall effect technique to derive the commutation sequence. Several design and simulation experiments were carried out to assess the performance of the open-loop and closed-loop control systems. The generated output of the BLDC, which are the rotor speed, voltage source, and electromagnetic torque were then measured and discussed. Several stages of testing were carried out to evaluate the performance of the BLDC motor. The results of the open-loop and closed-loop systems are compared and analysed to determine which system is best suited for the BLDC motor. The closed-loop simulation results for loads of 1, 5, 10, 15, and 20 Nm with a reference speed of 1000 rpm, 2000 rpm, 3000 rpm, and 4000 rpm. As the load increases, the rotor speed remains constant. This project's closed-loop control system demonstrates that the rotor speed is the same as the desired speed even though the load is increased until 20 Nm. As a result, the closed-loop system is preferable for controlling the desired speed of the BLDC Motor. This is due to the closed-loop system provides the same information to the speed reference, and the mean value of electromagnetic torque rises. | |
