All of that and more are discussed in this previous tutorial about DC motor control with L293D driver. Check it out and come back to resume developing our DC motor driver library for STM32 microcontrollers.

The torque and speed vary with load as indicated by this torque-speed curve. Looking at the graph below, let’s consider a motor rotating at speed ω0 with torque T0.

In other words, energizing of U, V, and W must be continually switched so that the resultant flux keeps moving, producing a rotating field that continually pulls on the rotor magnet.

Generated because of the constant switching of the commutator, it affects neighboring electronic components. To reduce it, you could implement different filters that protect the wires from EMI.

If this causes many problems, a switch may be installed between these components to shut off the circuit when needed. Once both ends of the wire are connected, the circuit will be ready.

It can be physical contact with a rotary potentiometer or an optical encoder. I’ll try to include a similar tutorial for this in the future as well. But you can search this topic em linha to find more ideas and techniques to achieve servo motor control using DC motors.

Entrusting your project to an external engineering team, make sure they have relevant skills and expertise. An experienced developer will consider each nuance and figure out how to design a DC motor controller for your particular project. 

There are different types of DC motor controllers along with the principles of their classification. The infographic below shows this variety.

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

If running at more than a 5 amps, I would beef up the diode with a power schottky diode in a 2-lead to-220 package such as a DSS25. Great circuit, I used a similar one to control my brushed RC car before I went to brushless.

In this tutorial, we’ll be discussing DC motor speed control with STM32 PWM and L293D H-bridge motor driver. I’ll also show you the DC_MOTOR library (driver) that I’ve developed for STM32 microcontrollers and discuss how it works and how it’s been built in this way. And we’ll create 3 different example projects with STM32 uC and DC motors.

First to begin with, an electric motor is a machine that uses electricity to turn a shaft, thereby converting electrical energy into mechanical energy. Electric motors are broadly divided into the following three types.
