Hope this article has helped you to better understand how to incorporate DC motors into your electronics projects! Leave a comment below if you have any questions.
This example will show how to model a DC motor's speed using different approaches in Collimator. The three approaches involve simulating diagrams from a differential equation, a transfer function, and a state variable model. Then, we will design and simulate a PID controller for the DC motor speed.
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.
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.
type DC Motors (permanent magnet types), our range does not apply to brushless which uses a completely different method to control motor speed than a brushed motor does!
Let's try a variation of the Project 2 experiment: control the speed of the DC motor with an ultrasonic distance sensor. Of course, we'll use an Arduino and the L298N motor driver.
Entrusting your project to an external engineering team, make sure they have relevant skills and expertise. An experienced developer will consider each nuance and figure out how to design a DC motor controller for your particular project.
Prepare the power supply. If using a power pack, install the batteries so the + and - sides are facing the correct directions in the housing. If it can be done, keep the power supply off for now.
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.
Another option that you can choose for your project is a GaN transistor made of hard and extremely durable semiconductor material. It can resist high temperatures and operates at very high frequency and voltage ranges.
A 10k Ohm potentiometer is used here. The ends of the resistive track are connected to 5V and ground, respectively, and the wiper pin is connected to the A0 analog input pin of the Arduino UNO.
Here’s a basic circuit of the 555 Timer operating in an astable mode and we can notice that the output is HIGH when the capacitor C1 is charging through the resistors R1 and R2.
Before going further we need to discuss the H-BRIDGE. Now this circuit has mainly two functions, first is to drive a DC motor from low power control signals and the other is to change the direction of rotation of DC motor.
In this tutorial, we will cover the basic principles of DC motors and show you how to control the speed of a motor using PWM, an H-bridge circuit, and the L293D motor driver.
