Controllers are classified into digital and analog versions. The main difference between a digital DC motor controller and its analog variant is that the former comprises microcontroller (MCU) based hardware and firmware.
DC motors may find use in different devices and systems depending on their characteristics. Thus, stepper and servo motors power machines that require precision positioning such as:
Note that: I’ve deleted the auto-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.
In the circuit diagram, slider of the potentiometer is connected to analog input pin A0 of arduino. Resistor R1 limits the base current of the transistor Q1.
And if you’re going to use my library as it is, you’ll have to keep in mind that the speed values you’re sending to the control function should be correct for the resolution you’ve selected. For example (Desired Resolution = 8bit, so the max speed is 255 & min is 0) and so on.
This one could be the simplest example of PWM control using arduino. Here the brightness of an LED can be controlled using a potentiometer. The circuit diagram is shown below.
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.
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).
Once the distance is calculated, the move_motors function is called, and the distance is passed as an integer parameter. Just like in Demo 2 Version 2, motors are moved in one of two ways: if distance is 50cm or less, the motor speed is proportional to the distance.
Typical configuration: three coils with 120º spacing. Driven by controlling the phases and coil currents.
In a DC motor, different speed controls can be achieved and hence they are used for many adjustable speed drives. The different mechanisms of speed control can be deduced from the speed equation of a DC motor.
As you’ve seen in the DC_MOTOR.h file, the provided APIs do all the basic functionalities that you may need from a motor driver library.
It induces a variable voltage in the generator. The variable voltage is given as the input for the DC motor, which makes the main motor to rotate at different speeds.
Designing a high current DC motor controller schematic, we used an IGBT that combines features of power MOSFETs and bipolar switches. It provides a high level of current and is well suited for complex power electronics systems.
