A lot of Engineering projects and tutorials for the students to help them in their final year projects and semester projects.
In this method, the field winding is excited by a constant voltage but the armature winding is supplied with different voltages through switching devices. The speed of the motor will be proportional to the armature voltage.
If you connect everything correctly than if you turn the potentiometer anticlockwise the motor will spin faster and if I turn the potentiometer anti clockwise the motor will slow down.
The pads of the components that need to be connected to Ground are set to Ground through the Pad Properties tab, where we need type GND into the “Net” label when the pad is selected.
You can always show your support by sharing my articles and tutorials on social networks. It’s the easiest way to support my work that costs nothing and would definitely be appreciated!
As the name suggests, the purpose of the L293D motor driver is to drive DC motors. The L293D is a popular motor driver IC that has a built-in H-bridge circuit that can drive two DC motors simultaneously.
You can find a DC motor in many electronic appliances around you, including in an electric toothbrush, a washing machine, a printer, and a car. A motor controller ensures the efficient and safe operation of the motors used in these appliances.
The speed of a DC motor is directly proportional to the supply voltage. A simple way to control the speed of a DC motor is to regulate the supply voltage with pulse width modulation (PWM).
The basic idea behind PWM is that it switches the supply voltage ON and OFF very quickly. By adjusting the length of the ON/OFF pulses, we can set the voltage to anywhere between 0V and the maximum voltage. We will use this PWM signal to power the motor directly.
A DC motor has some significant advantages, and one of them is the simplicity of its control system. Here, we’ll tell you how a DC motor controller works and how you can use it.
If we start to reduce the maximum voltage at which the motor rotates at maximum speed, the speed of the motor also starts to reduce. In this way these enable pins are helpful to control the speed of the DC motor.
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.
PWM is a method through which we can generate variable voltage by turning on and off the power that’s going to the electronic device at a fast rate.
Compliance with the system requirements is the basic principle you should follow while selecting components for your DC motor controller schematic. This relates to an MCU, gate drivers necessary to control the transistors, and other components.
