A direct current (DC) motor is the oldest type of electrical motor that has gained widespread use in a variety of electronic devices and equipment. DC motors have different arrangements and operation peculiarities.

In this article, you will learn about the working principles and applications of this electronic device. We’ll tell you about the design nuances of a control unit used in one of the most popular electrical motor types – a brushed DC motor.

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.

Electronics and semiconductor manufacturers offer a rich selection of hardware and software components that you can use in your project. For example, in building a BDC motor controller circuit for the robotic lawn mower, we used STM32F4, which is part of the STM32 ecosystem for motor control.    

Initialize the BUTTON & DC_MOTOR in the main application, start the DC Motor, read an analog potentiometer with ADC. And use that reading to control the motor speed in the main loop of the system. Read the buttons and use it to flip the direction of motor rotation. Repeat!

Additionally, such gate drivers are not interchangeable. If they become discontinued, you’ll have to redesign the schematic together with the printed circuit board.

We can use an H-Bridge circuit to do this. The H-Bridge circuit derives its name from the four transistors that look like an “H.

Here we can simply drag and drop the downloaded zip file of the gerber files. After uploading we can once again review out PCB in the Gerber viewer. If everything is fine we can then select up to 10 PCBs and get them for only 2 dollars.

A linear regulator keeps the output voltage at a constant level with a resistive load. The output is stable no matter what input voltage is supplied by the power source.

The purpose of a motor speed controller is to take a signal representing speed from some sort of adjustable control (for example a Potentiometer or a Hall effect device) and to drive a motor at that speed.

A brushed DC motor is one of the most common types of electrical motors. It is widely used in consumer electronics, robotics, low-power industrial and automotive applications. A BDC motor, as well as its control system, has a simple construction and easy implementation.

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.

You can see how, from a humble beginning, you can start branching out and experimenting with different types of hardware, to gradually reach more interesting configurations.

Disassembled encoder. The encoder converted the rotational speed and direction of the motor into digital signals recognized by the controller. When changes occurred, the controller adjusted the control actions as necessary.
