55t or 65t

[Rider385]

ok its that simple more turns= more torque

for a crawler you want torque so why not go with the 65t ?

[DISTURBIN' tha PEACE]

I got 65t's in my stick w/8t pinions works well.
I might go to 9t pinions. Also, I use 7 cells.

[Rider385]

works well or better than the 55t?

[Mad Scientist]

I say go with the highest count you can get, then compensate with gearing or more cells if you want more speed. The main reason most people have been running 55 turn motors, is that up untill recently, that was the only option that was offered for lathe motors.

ok and what is a lathe motor what is the difference betwen normal lathe and brushless?

I currently run a 65t and like it's performance,although theres always bigger and better out there. I've got a motor coming that will probly make my 65t seem like a 280 sized 10t Coarse,I'm just guessing right now,untill I get the motor and try it I won't know for sure.

I hand wound my current 65t and have wound my own 45t,55t,65t,70t and 80t. I honestly feel that winding your own is best. For one,you can do it cheaper than buying a motor and it takes 30 minutes or less in front of the T.V. Two,it seems that suppliers are always running low on these high turn motors. I see new threads on a daily basis,"where can I get a 55t","who's got em?" and many others. Winding your own,you go get the wire and wind away,no waiting or any kind of backorder deal to deal with.

Jammstang or however he spells it,did a thread on the dyno results of various motors. Good thread with some good info on the different turn motors. I personally feel the 65t is better,some guys however feel the 55t is better. Both are good motor and you can gear up or down depending on what you want for a final gear ratio. The 65t will draw less juice,hence helping runtimes.

Standard brushed motors have wire coiled around an armature, and magnets lining the can. Brushes transfer the power to the armature as it spins. Lathe motors are the same, but generally have very high wind counts, and are used for comm cutting lathes (hence the name). Brushless motors have the coils mounted around the inside of the can with a cylindrical magnet mounted on the motor shaft, where the armature would be if it was a brushed motor. Since the coils do not rotate within the motor, no brushes are needed.

great thanks mad scientist and ill go with the 65t but, i work at my lhs, i looked today in the system and we can only get 55t but the owner said he has to call so we can get the 65t.

[JohnRobHolmes]

both the 55t and the 65t have the same power. They just produce it at different voltages and amperages. The 65t will give you longer runtimes at the same power level, but at a higher voltage. Both work fine for a crawler.

[Rider385]

so you mean i need to run 65t at a higher voltage if i want more speed or just to get it running.


because i'm starting at this now so i'll go really slowly to get over obstacles by using 4ws.

this is a basic fact of all motors. More voltage is more motor speed. The 65 turn will work just fine on 6 cells, but if you have any 7 cell packs im sure it will do great too.
