Is there a break in procedure for electric motors?
Thanks

WAXER128,
If you're asking if a 'break-in' should be done on every electric motor, then the answer is not really. Depends a lot on it's end use. Motors for 'go fast' stuff won't be hurt by a 'break-in' period, sort of shapes the brushes to the rotor (for those motors having brushes). Is a 'break-in' done at the factory? Usually, no. They do test to see if they run, but that's not really a 'break-in' is it? For motors intended for the 'slower' boats a 'break-in' isn't really needed, sort of. Don't know about you, but a motor I put in a boat gets more 'testing' than probably required for a 'break-in' - lol. (Haven't had to 'break-in' a motor yet, but that doesn't mean a lot.)
How to do a 'break-in'? Dunking the motor in sterile water and running it for a while seems to be one 'accepted' method. Just plain old running it is another.
So, on the 'average', a 'break-in' probably isn't needed.

(The 'other' 'break-in' procedure requires the use of a crow-bar or large hammer. Yeah, I know, but how could I resist?)

Hi Waxer, I break in my 700 motors for my competition boats by running them submerged in water; only half submerged, when the front bearing is a ballbearing!

I run the motor on 2-4 V, so it barely turns and allow it to run until the water turns dark(ish) then I check if the brushes have set sufficiently.

If available, blow the water out by compressed air and allow the motor to dry out completely (warm surrounding) , oil the rear bearing (both if the motor is a 700 SC) prior to running it.
With the smaller motors like the 400 and 600 motors, I don't bother.

Works for me.

Regards, Jan.

Yup! :cool:
