The many applications for motors are well known. But have you ever discovered how it really operates using motor driver ? If not, find out in 2 minutes of reading.

Motors, followed by solenoids, pneumatics, and hydraulics, are the most often utilized actuators in electrical devices and machines. From a straightforward vibration motor inside a phone to intricate stepper motors in CNC machines, these DC machines are common. To control a motor using a microcontroller or processor, you need a motor driver or motor controller. Depending on the kind of motor and control needed, there are many different sizes and shapes of motor drivers. In this post, we will only discuss DC motors and demonstrate how to use a Motor Driver to operate a DC motor.

What is motor driver

An integrated circuit chip known as a motor driver IC is used to manage motors in embedded systems and autonomous robotics. The two most popular motor driver ICs used in low-powered robotics and remote-control cars are L293D and ULN2003. There is no doubt that a motor driver is something that makes the motor move in response to the inputs or instructions delivered . It controls a real motor that requires high input voltage by listening to the controller’s low voltage. Simply put, a motor driver IC regulates the direction of the motor in response to commands or instructions.

How does Motor driver works

The motor driver receives signals from the microcontroller first. The motor is then driven by the reference voltage that has been given after the signals received by the motor driver have been translated and stepped up. There are two voltage input pins on the motor. While pin 2 switches the motor OFF by providing OV at the output pin, pin 1 turns the motor ON by providing a voltage equal to the reference voltage. The motor driver is in charge of this entire operation. Using a tiny voltage signal from a microcontroller or control system, we employ motor drivers to supply the motor with high power.
