We have explained PWM in this tutorial using 2 examples which will help you learn how to control LED brightness using PWM and how to control DC motor speed using PWM.
Do not cut off more than the plastic insulation so that the copper wire is exposed. Cutting more than the insulation will damage the wires ability to properly carry current and may prevent the circuit from working.
A controller of a brushed DC motor manages the speed and torque of the motor by regulating the current and voltage injected into it. The major design and working principles of BDC motor controllers can differ between their types.
As with Project 2, the 9V batteries depict the motor battery power supply. The black module in the middle of the breadboard depicts the L298N motor driver module with the connections as described earlier.
Connect the left pin of the potentiometer to the drain pin of the mosfet, the middle pin to the gate pin of the mosfet, and the right pin to the negative wire of the 9V battery clip.
There are different types of speed control of dc motor. Let us discuss, how the speed can be controlled with the above parameters.
I have tried this circuit and I find that the motor makes an audible noise because of the ~500Hz frequency of the PWM, I have tried changing the timer prescaler but It ends up putting the analogRead out of timing too.
The library has hundreds of thousands of components so I didn’t have any problem finding all of the required components for this PWM DC Motor Speed Controller circuit.
In proportion to the reduced voltage, the speed is reduced. However, the field current remains the same as the field winding is directly connected across the supply voltage.
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.
Using any method of connecting the wires, securely attach the resistor to the power supply using one wire, attached on both ends, or by connecting the components directly together. The amount of resistors here may vary depending on what speed the motor must run at.
A brushless DC motor controller uses sensors to specify the rotor’s position. It switches the current in the windings with the help of transistors. In our article dedicated to a BLDC motor controller, we provide a detailed description of its working principles and design features.
The direction of the motor’s spin can be changed by swapping the wires connected on either terminal of the DC motor. Due to the vast variety of potentiometers, the range of speeds may not be optimal for a specific application and a different type may be needed to have more fine control over the motor or to achieve a lower range of speed.
There are several ways to generate the PWM signal for the motor, but in this tutorial we will use the 555 timer. Here’s a schematic of the circuit:
