You basically right-click the project name in the IDE’s navigator and choose to create a new > source folder. And name it ECUAL and go to the GitHub repo, download the files and copy the “DC_MOTOR” folder and back to the IDE, right-click on the ECUAL and paste the library into it.
To maintain a process parameter at a desired level, engineers often use the PID mechanism in feedback control loops.
So we had to add a CPLD that could read high frequency signals. If you are planning to build a brushed DC motor controller with feedback, make sure your MCU can provide this opportunity.
003kHz as shown below. Not bad right? of course it’s not an exact value like the resolution but it’s just as fine as we won’t need that much FPWM accuracy in DC motor control applications.
Thanks. The maximum current output depends on the transistor, in my case it’s TIP122 which can handle current up to 5A.
This page will show step by step the relationship between speed, torque and drive voltage of a DC motor, and how to control it.
We’ll have to do this step just to have the TIM_HAL files added to our project by CubeMX. And also it gives us a startup configuration for the PWM channel of that specific timer module as we’ll see hereafter. This is the best way to keep the code generic and portable to any STM32 microcontroller.
When the speed is to be increased, the two motors are connected in parallel with the starting resistance in series, as shown in figure(b). The starting resistance is gradually cut out when the motor picks up the speed.
Using the switching devices, the armature voltage is increased or decreased. With respect to the change in voltage, the speed varies. This method of controlling the speed is not much adopted in real applications.
It is an efficient method of speed control of DC motor. When two or more similar series motors are employed in pairs, speed control can be achieved by combining the series resistance with motors in series and parallel connections.
When the entire field is connected, the motor runs at the lowest speed. The speed can be further increased in steps by cutting out the resistance in the series turns. This method of speed control is used in electric traction.
The PWM controller accepts the control signal and adjusts the duty cycle of the PWM signal according to the requirements. PWM waves with various duty cycle are shown in the figure below.
We can use the Silk layer to add text to the board. Also we are able to insert an image file, so I add an image on of my website logo to be printed on the board. At the end using the copper area tool we need create the ground area of the PCB.
The switch is to change the direction of rotation of motor. The capacitor here must not of a fixed value; the user can experiment with it for a right one.
