Buying a breadboard or a breadboard kit make building circuits easy and quick. There are a variety of kits on-line that include all of the components needed to build either of these circuits.

Semicon Media is a unique collection of em linha media, focused purely on the Electronics Community across the globe. With a perfectly blended team of Engineers and Journalists, we demystify electronics and its related technologies by providing high value content to our readers.

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.

Hey I'm Dejan, a maker, a techie and a mechatronics engineer. I love making electronics and robotics projects for you to learn and make something cool on your own.

Thanks. The maximum current output depends on the transistor, in my case it’s TIP122 which can handle current up to 5A.

As we have seen, we drive BLDC motors by continually changing the directionality of the flux produced by the coils. The permanent magnets on the rotor continually chase the shifting rotating magnetic field, causing the rotor to turn.

Building an autonomous robotic lawn mower, we installed a reversible DC motor controller with a PWM switching regulator for a brushed DC motor chosen by the customer. The idea was to develop a low power consumption and budget-friendly system. 

Appropriate inverter circuitry is therefore essential for driving BLDC motors. Note that inverters can also be used with AC motors. But when a term such as “inverter type” is used with reference to consumer electronics, it is usually referring to a BLDC motor.

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.

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.

A 10k Ohm potentiometer is used here. The ends of the resistive track are connected to 5V and ground, respectively, and the wiper pin is connected to the A0 analog input pin of the Arduino UNO.

A typical DC motor has two connecting leads – one for the negative terminal and the other for the positive terminal. If you reverse these terminals (changing the polarity), the motor will spin in the opposite direction.

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.

The output of the 555 timer can sink or source a current of 200mA to the load. So if the motor that we want to control exceeds this rating we need to use a transistor or a MOSFET for driving the motor. In this example, I used a (TIP122) Darlington transistor which can handle a current up to 5A.
