The Engineer's Guide to AC vs DC Motors

Electric motors serve different purposes, but their core function—to convert electrical energy into mechanical energy—remains consistent. In our latest Hardware Guide post, we break electric motors into two categories: AC (alternating current) motors and DC (direct current) motors. We discuss the pros and cons of each type and then get into detail about the best use cases for each type of electric motor. We explain how AC and DC motors convert electrical energy and compare their construction.

Types of electric motors: AC motors and DC motors

In the end, the type of motor you choose will be based upon the type of product you're building. You'll need a DC motor if you’re using circuit boards and batteries, and if you need to fine-tune your speed controls. If you’re looking for power and efficiency, and need something long-lasting, an AC motor is the best choice.

Check out the post on the Hardware Guide to learn more about AC and DC motors and to choose which one is right for your next project.
