Motor control on STM32
Preface Here, there are many online resources available for reference, such as the video tutorials on FOC control principles and motor application development based on STM32. This discussion focuses on the code generated by ST’s Workbench after setting up the parameters, mainly on the program architecture and important code explanations. After understanding the architecture, users […]

Preface On the ST side, Motor Profiler and MotorControl Workbench are introduced to facilitate the complete construction of the underlying program and provide basic APIs for applications. They are relatively easy to use for beginners and have the advantage of having all their code fully open for viewing, including the writing methods of each API.

Preface After discussing all the mathematical transformations, we come to the final step of FOC control. First, let’s take a look at the Three Phase Inverter shown in the diagram below, which is generally included in the motor driver. The green box typically represents the MCU control calculation. The final complete FOC algorithm The physical

Preface In the previous section, we discussed the decomposition of feedback signals. In this section, we will delve into the introduction of input signals. PWM to SPWM We need to drive a three-phase inverter circuit, and if we use only switching, we will get a control signal similar to a 6-step square wave, which is

Preface In the previous chapter, we introduced the types of motors and briefly described their control methods. In this chapter, we will delve into the mathematical model and FOC control method in depth Control state Here you can refer to the dynamic diagram of the left image, where it can be seen that different current

Preface We will be discussing the ‘Y-type winding brushless DC motor’, and will explain the motor type, principle of rotation, control methods, theoretical control, and step-by-step implementation. are shown in the following figure. Principle of Motor Rotation The two circular magnets in the figure below will rotate due to the rotation of the upper magnet,
