How To Make A Brushed Motor Faster?

Every racing enthusiast is passionate about their RCs. If you are one of them, you must know the tactics of RCs like how to improve performance, how to break-in, how to maintain the engine, etcetera.

But don’t know how to make your RC brushed motor faster? Read this article thoroughly and learn the methods of how to make a brushed motor faster and improve its performance.

We will try to present every possible point broadly so that you can understand how to do it. Therefore, stay with the article till the end.

How To Make A Brushed Motor Faster?

Why Will You Need To Make It Faster?

Isn’t it evident that RC motors will not perform the way they used to? That is because mechanical parts need proper maintenance if you want the best out of them. There will always be a problem like broken gears, dirt inside the motor, old coils etcetera. These are responsible for the performance drop of your RC. When looking for the techniques that will make the RC faster, look through these reasons for once.

How to Make a Brushed Motor Faster?

Suppose your RC motor is not performing well, or it has become slow. What can you suppose to do to make the motor faster, like before or than before? First of all, you have to find out if there are any problems with the motor like broken gear, old copper coil or insufficient magnet power. Then necessary steps can be taken to make your brushed motor faster.

1. Change the Gear

There is a great possibility that your motor might be broken after a long time of use. Therefore, a simple gear change will solve the problem and make the motor faster. Even if the gear is not broken, changing it will affect the performance. But how would you know if the gear is broken or damaged? If you want to change the gear, then the only way it disassembles the motor. But it is not easy to do it because all the brushed motor is sealed. Tools you will need:

  • A small narrow head screwdriver
  • A long nose plier
  • A hammer (optional)

How Should You Do It?

At first, try to remove the gear with the plier by free force of your hand. If that is not possible, then place it between two metal or strong wood. Then try to remove gear from the shaft with the hammer. As the gear is removed, now you can install a new one. Again, use the hammer while installing the gear. But do not give much force that it breaks the gear. You can also use some other tools if you find it suitable to remove the gear from the motor.

After the installation, it is time to check the motor. You will notice the difference in speed in spinning. An RPM meter can be used to measure the increment.

2. Upgrade the Coils

If you want to make your brushed motor faster, then upgrading the motor coil is most probably the best option for you. To upgrade the copper coil, you will need some tools. And here is the list:

  • A small narrow head screwdriver
  • New copper wires
  • A tool for shouldering

Process Steps

At first, disassemble the coil and magnet part from the motor. Then remove the old copper wires from the shaft. Make sure no extra wires are attached to the shaft. You should use similar thick copper wires to the old ones. That is because if the thickness does not match, you might damage the whole motor. Now get the shouldering kit and attach the starting point of the wires to the commutator. Then you can twist the wires into the frame. Just make sure the wires do not get loose while wrapping it to the frame.

The frame has three parts where the copper wires are placed. When you have wrapped 70 rounds to one part, then you should get to another one. The manufacturers fix the number. If you want such preciseness, you will find the number around the manual or contact them. After completing the wrapping process, attach the end of the wire to the other part of the commutator. You should also replace the brush. Now the motor is ready to roll. You can test its performance by RPM meter.

3. Clean the Commutator

Sometimes filthy commutator might drop the speed at a significant level. Therefore, clean the commutator whenever you see any performance drop. All you need is sandpaper or steel wool or whatever you have to remove the dirt from the commutator. Scrub the sandpaper over the commutator. But be careful about the force you are giving. It is because too much imprint can lead to further damage to the brush, wires, or connection of commutator with the wires.

Then you will notice the speed difference of the motor.

4. Other Methods

There are some small upgrades by which you can boost the speed of your brushed motor.

Upgrade Magnets

Old magnets will reduce the RPM of the motor. If you want a boost, then you should get upgraded to new magnets. It will not make any significant difference. But in racing, any slight difference will decide the result.

Clean the Motor

A filthy motor is another reason to lose speed. You can use either try dry break-in method or the wet break-in method to clean the motor. It will keep your RC brushed motor in a tip-top condition.

Check the Connection with ESC

If any connection with the ESC gets loose, then you will notice the difference in speed. It would be best to check the connection always.


We hope the discussion has given you a proper idea of how to make a brushed motor faster. You may try these methods to improve the performance of your RC motor or exceed the speed. We recommend staying cautious while you are applying any of these methods. Wish you a piece of good luck.
