Electric motors

The main question concerning electric motors is: brushed or brushless?

  • Brushed pros: cheaper, simpler, better for off-road.

  • Brushed cons: heavier, bigger, worse power efficiency (75-80%), they wear out in time.

  • Brushless pros: long lifespan, much better speed and handling, better power efficiency (85-90%).

  • Brushless cons: much more expensive, worse for off-road.

So what should we get? It depends on your budget, but brushed motors work just fine, and besides, for self-driving purposes, you don’t need a RC car that drives 100 KPH.

It’s always possible to swap out a brushed motor for a brushless later on.
