Explain Some Thing Real Quick

hi guys I am wanting to purchase a upgrade lectric motor....but alot of them say "23 turns" etc.....how fast is that in RPM.....23,000 RPM?

You have it the wrong way.
The higher the turns ... the lower the RPM
However with a low rpm you get more torque, and thus better accelleration.

Stock motors, (that come with most Ready to runs cars) are 27 Turn (simply put, the wire is wrapped around the armature 27 times)
most stock speed controllers will handle down to about 20 - 21 turns before frying. make sure your ESC can handle whatever motor you choose.

Oooops ... looks like I oversimplified .

This might be a bit clearer:

The higher the turns ... the lower the RPM .. the lower the amps .. the greater the efficiency
(in other words, it uses less power, goes further on a battery but is weaker torque)

AND

the lower the turns..the higher the rpm .. the higher the power and torque
(in other words, it accellerates faster, goes faster, is less efficient and empties your battery sooner ... but thats how you win races, right )

How much is the difference ? Well a "standard" speed 600/mabuchi 540 motor might draw 90 amps at the point of startup, falling to about 20 amps when running. But a "hot" 540 with 20 wind might draw 200 amps at the moment of startup, and later on, running faster, it takes more amps to maintain that greater speed.

Everything has a price though, it generates more heat, so to stop it melting down it must be constructed of better materials, cobalt magnets, gold plated connectors, ballraces, etc. That is why the hot 540/600 motor is 50 - 100 €, but the standard one which looks similar is only € 10 - 15.

Hope this is a better answer.

thanks for clearing alot of things up....I have a New Bright Ultimate Performance Vehicle Mustang GT Concept and it has an 18,000 RPM motor...so that would be about a little less than 20 turn right?....I want to get a 36,000 RPM motor..how many turns is that?...thanks for all the help

motors generally aren't graded by RPM, though it's possible there'a atable relateing of winds vs. RPM
here are a few link to some motor maker's websites, thye may help:
