Depending on the voltage necessary for the motor’s operation, you can choose a low or high voltage controller. A switching regulator works well for controllers with a wide operating voltage range.
The characteristics of a DC motor are represented by a torque-speed curve that slopes downward to the right, with torque as the horizontal axis and speed as the vertical axis. The speed is highest when there is pelo load, falling away to the right until maximum torque is reached at zero speed.
Motor power relies on the current supplied by the power source. Thus, a low-power BDC motor needs a low current controller and vice versa. A high current DC motor controller typically uses a switching regulator.
In fact, there is strong reasoning behind this being true. Which is a topic for a future article I’ll be publishing to show you my testing results and how to model a DC motor and take the parameters to MATLAB and simulate what’s going on and how FPWM affects the actual motor speed which can be weird to hear.
With some viable alternatives available now, it’s becoming hard for a BDC motor to stay competitive in high-power electronics.
The output of the IC needs to be connected to the base of the transistor through a resistor, and in my case I used 1k resistor. For preventing any voltage spikes produced by the motor we need to use a flyback diode which is connected in parallel with the motor.
It’s been and will always be a free resource of information. So, please consider supporting this work if possible.
Test the circuit. The DC motor should now be spinning if all components are securely connected. The resistance provided by the resistor(s) determines the speed the motor will run. If the motor is not running, check all the connections to make sure the circuit is securely connected. If the motor still doesn't run, check that the battery is not dead by connecting it directly to the motor and replace or recharge if dead.
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.
It is an efficient method of speed control of DC motor. When two or more similar series motors are employed in pairs, speed control can be achieved by combining the series resistance with motors in series and parallel connections.
By regrouping the field coils the resistance in the field winding can be varied, which will give the required speed. This type of speed control is used for fan motors.
The two most simple ways to control the resistance is to use resistors and potentiometers. Resistors provide a fixed resistance of any value while a potentiometer provides an adjustable range of resistances. When either are used correctly in a circuit, they provide control over the speed of the DC motor. These circuits are most easily done using a breadboard; however, buying screw down components, using electrical tape, or soldering (if you are properly qualified) also works.
You basically right-click the project name in the IDE’s navigator and choose to create a new > source folder. And name it ECUAL and go to the GitHub repo, download the files and copy the “DC_MOTOR” folder and back to the IDE, right-click on the ECUAL and paste the library into it.
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.
