A couple of dummy questions

[edman87k5]

I am a noob to the scene. I am slowly modding my WK and don't understand some things. I plan on upgrading the motor soon and I do not understand what a lathe motor is! I know what a lathe for metal or wood shaping is, but don't think it has anything to do with a rc truck motor! Someone please explain. Do they require special esc? Last longer, smoother power, less batt draw? They do seem to be cheaper compared to a other motors, I might be wrong on this though.
Would a 45t lathe motor work with the stock electronics on a WK?
I have searched several different ways and cannot come up with what lathe really identifies on the motor!

welcome aboard"thumbsup" lathe motor is from a rc tire lathe,slow turning, great torque. the stock esc will hold it, but its best to upgrade eventually!8)

Yup, the lathe motor has alot more torque. it was probably one of my best mods to my crawler.

It's called a lathe motor because it's used on a very small lathe that is used for truing up motor shafts, comm's, and tire grooving and shaping. The higher wind rating allows more torque so that when you use it on the lathe (pushing against the object you're lathing), it won't stop the lathe from spinning, and it's not spinning so fast as to burn instead of cut.

For this reason, they make great low speed torquey motors for crawling. Used to be that you had to buy a motor meant for a lathe and just use it in the crawler application. Now the companies sell them specifically to put in crawlers, and they just kept putting the lathe name on them because people were already used to what that meant.

They don't really require a "special" ESC...you actually have more choices than if you were running a high speed wind motor like say a 19 turn. Reason is, most ESC's are limited to the number of winds it can handle and winds are like wire gauge...the larger the number the smaller the wire is, and the larger the wind number in these motors the less speed and more torque you get. Also the higher the wind number, the better it is with handling your input voltage meaning you'll have longer run times.

Boy, am I a talkative one tonight :roll: :lol:

That is the best description I have heard. Thanks for a real explaination.

I hate to be a smart ass, but winds and turns are two different things. Lathes are single wound motors, in anywhere from 35-85 turns. Meaning, in say, a 55 turn, a single wire is wrapped around the armature 55 times. In a double or tripple wound motor, 2 or 3 wires would be wrapped 55 times around each pole.
More turns=More Torque
Less Winds= More low RPM torque

what's the lowest turn lathe motor available? i need some more torque in my clod but i don't want it to be any slower(top speed) than stock.

Thats not possible man.
You sacrifice one for the other.

You get more torque, you lose speed.
You can't have both.

You're right, I was typing so fast that I used the wrong term. I meant turns instead of winds. Smart ass

Well, yes and no. If you want more torque and go with a higher turn motor, but also adjust your gearing...you can get more torque and keep your wheelspeed up. You can also add voltage. Plus, from what I have seen from some of the handwound motors...you could have a 35t motor that will get you some decent wheelspeed, but also have gobs of torque.

kinda going along the same lines but....i have a 75t and am looking for a bit more wheel speed...i am currently runnin 7.2V and am thinking of jumping to 11.1V. I have a tekin rebel II esc and wanted to check to see if it will stand up to the extra voltage. also what is the cheapest most effective way to get 11.1V because my budget is tight. i have a 3000 Venom stick right now and it would be great of i could have the same thing with 11.1V in a stick form. thanks for the help and sorry its a bit off topic but i figured it wasnt worth starting a new thread.
Thanks
