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.
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.
Should I oil my brushless motor?
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.
How long do Brushless RC motors last?
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.
Can 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).
Do brushless motors have bearings?
A brushless motor used in RC is actually quite simple mechanically. There are only a few moving parts in the entire assembly. Those moving parts are limited to the rotor containing the permanent magnets and the bearings that support it.
