Brushless vs Brushed Motor for RC Cars

If you are new to the world of RC cars, then you have probably come across the concept of brushless vs brushed motor. This guide explains the function of a motor and the difference between a brushless vs brushed motor.

Brushless vs brushed motor?

The motor is the heart of any electric RC car, and it generates the movement and speed of the RC car, hence choosing the right one can make a really big difference to the car’s performance.

The fundamental difference between a brushless vs brushed motor is that a brushless motor performs better than a brushed motor.

By avoiding the use of ‘brushes’ when converting electricity into motion, it reduces the amount of friction within the motor and hence making it more efficient as less energy is lost through friction. This means that brushless motors give your RC car more speed by giving it more movement for the electrical energy you feed.

Brushless motors also generally last a very long time, especially if you take good care of them. Avoid overheating, and remember to clean and re-lube the bearing if the motor gets wet.

I’m new to RC cars. Should I use a brushless or brushed motor?

These days, pretty much everyone is using a brushless motor over a brushed motor. While brushless motor is always technically better, it comes with a higher price tag than a brushed motor and is also much faster and hence tougher to control the car.

If you are new to RC cars, it might be better to purchase a RC car with brushed motor instead – it will provide all the power you’ll need in a first model at a much better price, plus you will learn to better control your first RC car.

Brushed motors run hot and tend to burn out every 15-30 batteries or quicker unless you take really good care of them. The Electronic Speed Controller (ESC) for a brushed motor has simpler electronics, and can be built cheap.

This is why brushed motor is typically used to power most toy grade RC cars and other toy grade remote control vehicles, and are also commonly used by beginner grade hobbyists.

Any drawbacks to using a brushless motor?

Besides the points to note above, the only likely drawback to a brushless motor system is the increased starting cost as compared to using a brushed motor. However, the long list of pros outweigh this con – you will need to replace motor brushes, brush springs, armatures or whole motors, which you will have to if you were using a brushed motor.

What maintenance work do I need for brushless motor?

You might need to clean or change the bearings, but as this is only ever rarely needed, it should not be classified as regular maintenance work.

We hope that this guide to brushless vs brushed motor will help you with the decision making!
