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.
DC motors may find use in different devices and systems depending on their characteristics. Thus, stepper and servo motors power machines that require precision positioning such as:
Note that: I’ve deleted the auto-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.
In the circuit diagram, slider of the potentiometer is connected to analog input pin A0 of arduino. Resistor R1 limits the base current of the transistor Q1.
With some viable alternatives available now, it’s becoming hard for a BDC motor to stay competitive in high-power electronics.
Additionally, such gate drivers are not interchangeable. If they become discontinued, you’ll have to redesign the schematic together with the printed circuit board.
). Another, “sensorless” way is estimate the position based on the magnitude of the current into each phase. In either case, the conversion of the coordinate space allows for direct control of torque-related electric current—allowing for highly efficient operation with little wasted current.
In this article, I will describe one last experiment that involves a DC motor. We will connect an ultrasonic distance sensor in the place of the potentiometer, and use that to control the rotational speed of the motors.
Connect the other terminal of the DC motor to the unused terminal of the power supply. If the power supply is not off or has no switch, then the motor may begin spinning once it is connected to the power supply.
Here’s the final appearance of the board and what’s left now is to connect a DC motor and a suitable power supply for it.
To change the direction of rotation the PWM of timer is connected to the second signal pin.
Implementation of vector control requires intensive mathematical processing, including the ability to rapidly solve the trigonometric functions needed to convert the coordinate space.
The maximum collector current 2N2222 can handle is 800mA. Keep this in mind while selecting the motor.
At the beginning of this tutorial, I’d like to make sure that all of you have the basic concepts behind DC motors operation and how we use PWM signals to control the speed of a DC motor. How an H-Bridge works and does the polarity-inversion to control the direction of the motor’s rotation.
