A lot of Engineering projects and tutorials for the students to help them in their final year projects and semester projects.

Great ideas! I am trying to build a PWM controller for a 24v 2A DC Motor. I will use it with my coil winding machine to wind transformers. I use transformers for my HAM Radio projects. You have also given me basic ideas for going ahead with pcb designing softwares. Many thanks and kind regards.

Most FETs on the market have a built-in diode that performs this function, so in that case, an external diode provides extra protection. For resistive loads, such as LEDs or heaters, there is no need for additional protection since they have a straightforward linear relationship between voltage and current.

This article has been viewed 28,894 times. A DC (direct current) motor is a type of motor that uses electrical current to create rotational motion. The speed and acceleration (torque) of the DC motor depends on the amount of current in the circuit. The amount of current going through the circuit depends on many different factors with the two primary variables being voltage and current. When using a fixed voltage to power the DC motor, such as a 9V battery or battery pack, the amount of current depends on the total resistance of the circuit.

If both ends of the power supply are touched, the circuit may slightly electrocute you depending on the current being supplied.

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. 

will increase and subsequently motor speed will decrease. Thus the speed can be controlled by varying the resistance in the diverter.

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.

A linear regulator keeps the output voltage at a constant level with a resistive load. The output is stable pelo matter what input voltage is supplied by the power source.

If you need a controller for a BDC motor, you can use an off-the-shelf device that fully meets your requirements. Or you can build your own solution with a tailor-made circuit design and custom firmware.

The average voltage depends on the duty cycle of the signal, or the amount of time the signal is ON versus the amount of time the signal is OFF in a single period of time.

The resistors can be any value but getting the exact speed needed from the motor requires testing with a certain range of resistors. The values of the resistors add up linearly so it is easy to calculate how to increase or decrease the motors speed by simply adding the values together. For example, two 1kΩ resistors wired together will act the same as a 2kΩ resistor.

The speed of a DC motor can be controlled by adjusting the voltage applied. This is because the speed and load torque of a DC motor is inversely proportional, and this translates with changes in drive voltage.

By carefully adjusting the current flow into each of the three phases, then, we can achieve a more continuous change in resultant flux, resulting in smoother motor rotation.
