Advanced Level

In this class I will show you how to control motors that are suitable for building go-karts, electric scooters, large robots, and much more. This requires a very different set of knowledge and skills than would be necessary for controlling a small hobby motor.

This class is intended for students with some experience working with motors, and mechanical systems. By the end of the class you will learn how to pick the correct power supply, build a control circuit, and adjust the speed of a motor. You will also learn how to make a circuit which reverses the direction the motor is spinning.

Motor control is demonstrated by a range of techniques such as using motor controllers with analog throttles and also with Arduinos and motor controllers.

I hope that you will come join me in the wild world or large motor control.

Lessons

Lesson 1: Large Motors

What precisely is meant by "Large Motors?" Over the course of this lesson, this question (and so many more) will be answered.

Lesson 2: Big Batteries

In this lesson we will discuss what you need to power large motors. Spolier alert, this means big batteries! Get ready to learn about some serious power supplies.

Lesson 3: Controlling Motor Speed

Once you can power up a large motor, the next step is learning how to safely control its speed. This lesson provides instructions for controlling the speed of a range of large motors using both analog techniques and Arduino.

Lesson 4: Reversing a Motor

Of course, controlling a motor speed in only one direction is half the story. In this lesson builds upon the last, and teaches you how to reverse the direction the motor spins.

Lesson 5: Further Considerations

Learning how to build circuits to control large motors is only the beginning of the story. Here are some suggestions for increasing the safety of your circuit, and some tips for going further.

Now that you have the skills, what are you waiting for?
