A current carrying wire in the presence of a magnetic field experiences a mechanical force that acts in a particular direction. To determine the focus of this force, Sir John Ambrose Fleming established a simple way that uses one’s left hand to visualize the relationship between the flow of current, the direction of the magnetic field, and the direction of the force. This simple yet highly effective technique became known as the Fleming Left-hand rule.

And now after knowing the ARR value, we can plug that into the FPWM equation and solve for PSC to find the approximate Prescaler value for the timer to get an FPWM that is as close as possible to the pre-defined value by the user.

But the current through each motor is half of the Completa current and so torque produced is lesser than series-connected motors. It offers great flexibility, reliable operation and power wastage is reduced.

Initialize the BUTTON & DC_MOTOR in the main application, start the DC Motor, read an analog potentiometer with ADC. And use that reading to control the motor speed in the main loop of the system. Read the buttons and use it to flip the direction of motor rotation. Repeat!

As soon as we used a discrete circuit, the responsibility for the major functions of the BDC motor controller rested with the MCU. Our engineers implemented algorithms that generated PWM signals with the required duty cycles and dead time. 

We can use an H-Bridge circuit to do this. The H-Bridge circuit derives its name from the four transistors that look like an “H.

Open-loop and closed-loop systems are fundamental concepts of control theory. Depending on the requirements or complexity of the electronic device, you can implement a control system either with or without feedback.

The flux can be varied by varying the current Ish through the shunt field winding. It is done by connecting a rheostat in series with the field winding as shown below.

Using the tracking tool we need to connect all the components. The tracking tool is quite intuitive and easy to work with. We can use both the top and the bottom layer for avoiding crossings and making the tracks shorter.

Once we are done with the design we just need to click the “Gerber output” button, save the project and we will be able to download the Gerber files which are used to manufacturing the PCB.

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.

Now look at Mode 4. Here we have current moving from W to V; this is the just the reverse of Mode 1. With a brushed DC motor, this type of current reversal would be achieved using brushes and commutator.

How to do position control using a DC Motor? well, this sounds like willing to create a servo motor. Basically, you’ll need to have some sort of feedback to tell the controller where is the DC Motor’s shaft.
