This paper focuses on the vector control of a BLDC motor with two different concepts of Pulse Width Modulation- the Sinusoidal PWM and the Space Vector Modulation strategy. The paper deals with the basics of a BLDC motor, its dynamic modeling and its speed control using two different strategies...
2. Basics of motor physics (II) Share Explore the principle of permanent magnets and electro-magnets, magnetic conductors, circuits and motor-generator principle. 3. DC motors (I) Share Go over the DC brush motor, its structure and function. 3. DC motors (II) Share Dive deeper into ...
Finally, the GA PID Tuner sub block performs the adjusting of the PID controller’s gains of both the bidirectional converter and the BLDC motor, having the error sets on each control as input parameters. The block diagram of Figure 4 shows the part of the proposed HIL structure corresponding...
And while the basics of motor design still apply, the addition of external control circuitry has added another set of design considerations to the equation. High on the list of design questions is how to obtain feedback for motor commutation. BLDC Motor Commutation Basics Before delving too far...
