Building a BDC motor controller can be quite simple, but it still involves some challenges. These can relate to both circuit design and firmware development. Let’s take a look at the things that may need your special attention. 

Great ideas! I am trying to build a PWM controller for a 24v 2A DC Motor. I will use it with my coil winding machine to wind transformers. I use transformers for my HAM Radio projects. You have also given me basic ideas for going ahead with pcb designing softwares. Many thanks and kind regards.

That’s why the DIR1 & DIR2 pins are not useful in this LAB, despite the fact that they’re already initialized and reserved by the DC Motor library for DC_MOTOR1 structure.

But the current through each motor is half of the total current and so torque produced is lesser than series-connected motors. It offers great flexibility, reliable operation and power wastage is reduced.

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.

In this article, we’d like to share our own experience in the design and implementation of a brush DC motor controller. You’ll also learn about challenges you can meet if you decide to build it yourself.

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.

Note that: I’ve deleted the Automóvel-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.

Rotation is maintained by continually switching the flux so that the permanent magnet is constantly chasing the rotating magnetic field induced by the coils.

Settings can be one digit at a time or fast sweep. The OMDC-MD series speed control settings are exact and repeatable. It will precisely control speed to ±1/2 RPM of set speed, long term. Pelo calibrations of the control are necessary.

PWM is a method through which we can generate variable voltage by turning on and off the power that’s going to the electronic device at a fast rate.

A look at the relationship between torque and current shows that these are proportional to one another. The ratio between the two is constant for a motor, with the relationship remaining the same regardless of changes in motor speed or drive voltage. This means that measuring the motor current on its own is enough to determine the motor torque.
