How do you test a brushed motor?

If you want to track this RC car that has a brushed motor and it is not working properly you may want to test your motor to find out if it is working or not. The easiest way to do that is to apply direct voltage to the +/- motor terminals.

You will need to unplug the red and black motor leads from the speed control and touch them directly to a battery’s red and black wires. This direct voltage will rotate the motor at a high rpm if it is working properly. 

You may also examine the motor itself and if you see any black marks on the coil on the inside of the motor the new know that it is burned up and no longer useful. 

How do you test a brushless motor?

Because most Traxxas RC cars have a brushless motor now, you will need to know how to test one of these motors if you think your motor is bad. Because a brushless motor is different from a brushed motor you will need to test it in a different way. 

The first way to test brushless motors is to simply spin the motor and make sure there are no sounds coming from the motor itself. 

The second way is to use another brushless motor and connect the wires from one to another and to spin the second brushless motor. When the second brushless motor is attached to your original first one and you spin the motor your first motor should spin as well. 

You can use either one of these methods to test the brushless motor to see if it is working properly or not.

What do I do if my Traxxas motor is just extremely dirty?

If your Traxxas RC car motor is extremely dirty you will want to clean it. The problem is many people are not sure what they can use on their motor to clean it without damaging it. No one wants to damage their motor on their Traxxas RC car as they are one of the most expensive components of the car. 

The best Way to clean out your motor on your Traxxas RC car that is dirty is to simply connect an air sprayer to an air compressor and use the compressed air to clean out any dust or debris that is in your motor. You can also use the cans of compressed air but make sure you do not hold the cans upside down as this will freeze the motor and damage it. 

Once you have the body off of the Traxxas RC car so you can clean the motor you will probably realize that the rest of your car is extremely dirty as well and you can use the same air sprayer to clean any debris and dust off of your car.

This is something that you should test often especially if you are planning on going to an important race as you do not want to get to the race only for your motor to stop working. 

Keeping your car clean is also important as dust and debris in your motor can cause damage to the motor as well as make it not last as long.
