Questions?? Motor info

I have no clue about anything about motors!
I'll be racing a 1/10 electric on-road
one of the classes is "13.5 brushless"
what does the 13.5 mean??
is 17.5 faster or slower?

another class is "10.5 brushless or 19T brushed"
what does 19T mean?

Do all ESC's work on both brushed and brushless motors?
I have a Tamiya silver can which I would also like to use

ANY INFO ABOUT MOTORS HELPS!!!!
Thanks!

The 'T' number is the number of turns of wire wound on the rotor inside the motor (its the part that spins). 17.5T is slower than 13.5T. There is a diff between brushed and brushless motors as far as 'turns'.


Some ESCs will run both brushed and brushless motors, but not all of them do.

Your silver can would be similar in speed to a non boosted 25.5 brushless motor. 21.5 non boosted is pretty close in performance to a Tamiya black can (sport tuned motor). The brushless motors have to be geared differently to brushed motors, but it's possible to get similar performance. At my club they often run zero timing 21.5 against black cans and the racing is pretty close.

On a brushless motor the windings are not on the rotor, they are on the stationary stator.

Came at this from more of a brushed prespective so if I made it confusing maybe this will help -

Look down about 1/2way for an explanation on how brushless motors work, its past the 1st part if their advertising.

This is Novaks chart on brushless motor specs - this has their listing of their kvs and turn equivalents -
