Your question: Can brushless motors be repaired?

At Global Electronic Services, we are highly skilled at all types of motor repair, including brushless repair, and if your motor can be repaired, we can repair it. We will replace any worn-out parts or parts that are in danger of wearing out, and return a functioning motor to you in usually five days or less.

What causes a brushless motor to fail?

However, it is now clear that the main cause of failure in brushless RC motors is heat. As a matter of fact, it has been documented that over half of all insulating failures in motors are a result of excessive heat. … Dust is another factor that may lead to a complete shut down in a brushless motor.

Do brushless motors burn out?

The only thing in a brushless motor that’s affected by running time is the bearings. The motor should run pretty much forever if it’s not abused. Check the motor-side connectors to make sure that none of the solder joints are loose or broken.

How do you service a brushless motor?

Just as with regular brushed motors, dirt can accumulate inside a brushless motor. We do not recommend the use of motor spray to clean the windings inside the motor can (stator). Racers who use motor spray simply make any problems worse. Instead, use a small brush and light air pressure to clean inside the motor.

Do brushless motors need to be broken in?

no such thing needed for a brushless motor. the break in was for brushed motors because it has… brushes that touch a moving armature. there is 0 contact in a brushless motor.

How long do brushless motors last?

Operating Life:



If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.

How does a brushless motor burn out?

The magnet in the Rotor will slowly fade over time and will fade faster with excessive heat and rapid heating/cooling cycles (like when racing outdoors in the winter on a clear but cold day). The Gauss meter will test the magnatism of the Rotor so you know if it has faded or not.

Do you need to oil brushless motors?

It’s true that we don’t have to lubricate brushless motors with ball bearings. Ball bearings are sealed with grease inside, so applying oil doesn’t really help much but actually could be counter-productive as well as making a mess because oil will attract dusts and dirt.

Do you oil brushless motors?

High RPM brushless motors have SHEILDED bearing not sealed. They require 1 drop of BUSHING oil (clings better) in each bearing before using that day.

Can you lubricate a brushless motor?

In a brushless outrunner motor, the parts that generate friction is the shaft bearings. After some usage it might get dry and start making noise, lubricant can help improving the smoothness and efficiency.
