Default How to maintain your Brushless motor??

Okay so obviously we have to do a lot less work on brushless motors than brushed motors. But what exactly should I do to keep my brushless motor performing??

After every race day? once a year?

...I would think it depends on the conditions you are racing under. (Indoor Carpet vs. Outdoor ...clean/dirty conditioins)

Keep your BEARINGS lubed.

what else can you do?

Some guys think they need to replace the Arm/Rotor every so often...but I know guys who have a LOT of time on their original..and haven't slowed down... (ALWAYS USE SINTERED if you are not already) Some say SINTERED just makes them run COOLER - but SINTERED's ARE faster~

The basics are to make sure that the bearings are in good working order (IE properly lubed) and that the inside of the motor is free of debris.

I recommend taking your motor apart maybe once a month just to check the bearings, and blow the motor out with some compressed air

NEVER use motor spray or other solvents as that there is a chance it can damage internal parts inside the motor.

Here's my maintenance schedule:

After 6 race days, I completely disassemble my BL motor, clean everything with motor spray, re-lube the bearings, and put the motor back together. I use LRP motors and the AE guys recommended the maintenance schedule I'm using...

I have not had it apart yet so this may be an obvious answer.

Do I need to take the bearings apart and clean them out and relube? Or just clean of the bearings and place bearing oil on them?

alot of sources say do not use motorspray or other solvents to spray out the can. The actual solvent can cause damage. Compressed air seems a good idea, and perhaps remove the arm and clean that with spray and then ensure you clean it with a lint free cloth

No you don't have to and shouldn't have to take the bearings apart. Simply ensure that they roll freely and are clean and then lube those babies up. If they feel grity when you try to spin them, you will need to flush them out, and there are many ways to do this. I simply spray them on one side with motor cleaner while spinning and it usually does the trick then I soak them in oil for a couple hours and spin them every now and then in the oil. Afther the first time that you clean the bearing out, (IE remove all of the grease from when they were new) You will have to maintain them a little more. Some may like that method others may not. If you can't get the bearing to roll freely then replace it.
