What do motor "sizes" mean?
_
I see designations such as "540" for normal RC motors. To what do these
sizes refer?
Kevin
completely wrong but it seems to work out like that

diameters. Any 280, etc. can have a longer can or shorter can. Thus longer
or shorter magnets. Longer magnets give you more torque.

It is the length of the motor casing in mm multiplied by 10, i.e. the
case of a 600 motor is approximately 60.0mm long not including the drive
shaft but including the length of any protruding bearings. Some 500
motors have external brush gear and the length of this is not included
either. So the actual motor size is just as big as a 600 and this is
also the case with some of the 400 size motors - all very confusing!
Because of their popularity, the Graupner Speed motor size has become
the de-facto standard for electric flight brushed motors.

for what the Germans say. Go to a hobby shop and ask to see a 280, 380, 540
motor.You will see what I mean.

Kevin
you are talking bollox
I have a 280 in my hand and guess what ??? its not 28mm dia and I also
have a 540 and guess what its not 54mm dia
all Tamiya type electric cars run on 540 sized motors and none are 54mm

I could go on and on, post me a model site that states a 540 motor or
any other model size motor where the number refers to the diameter, as
this is a model newsgroup, I don't think any one in the model hobby
world would refer a 540 motor being 54mm diameter and I have an Italian
electric glider for a 600 motor and the motor cannot be any more than
40mm in diameter or it wont fit in
so that's an English American and Italian company that back me up
I rest my case my lord

Guys,
I'm going to take a shot in the dark but I think that motor size that
they are labeling the motor by is based on Pulses.
