ok so i have been looking at drift motors and they all have the `T` value . and i am wondering what it means and what the numbers mean to how the car preforms. like are the lower numbers for more torc a and higher numbers for top speed or vise versa wacko wacko wacko help help help help help help help

Thats the long and short of it. T stands for turns, and it relates to how many windings of copper conductor there are around the commutator. Lower turn motors have less windings, but the conductor is thicker. High turn motors have more windings of a thinner wire.

Lower turn motors produce more speed, but they use more amps, the higher turns means it will have more torque, and will use less amps. This also means you get more runtime out of a high turn motor.
Its about finding what you want out of the car.

but what if you were to go brushless. would you get even longer run times of a motor with a similar rating. in this example using nimh batteries.

Essentially the same applies but a 10T brushed motor is not equivalent to a 10T BL motor, they are measured differently (cannot recall the ratio)
BL motors are measured in K/v which essentially means rpm per volt. So if you have a 3000KV motor running on a 7.2v battery, you will have max rpm of (3000 x 7.2 = 21000rpm). Opposite to the way the turns theory works, the lower the KV, the torquier the motor, and more runtime. High KV, lots of revs, less runtime.
It does not matter what battery you use, but lipo when fully charged is about 8.4v, so do the math on the KV thing.
All of this is very dependant on what you want to do, and your budget of course.

Here's a quick reference for you..

Quote :

Castle Creations CM36 brushless / brushed equivelent:
S7700 (7,700kV) = 6-turn
S6900 (6,900kV) = 8-turn
S5700 (5,700kV) = 10-turn
S4600 (4,600kV) = 16-turn

LRP Vector brushless / brushed equivelent:
X-11 3.0 (11,400kV) = 3-turn
X-11 3.5 (9,800kV) = 3-turn
X-11 4.0 (8,600kV) = 4-turn
X-11 4.5 (7,800kV) = 5-turn
X-11 5.5 (8,100kV) = 7-turn
X-11 6.5 (6,900kV) = 9-turn
X-11 7.5 (5,900kV) = 11-turn
X-11 13.5 (3,350kV) = stock 27-turn

Novak SS/EX/Velociti brushless / brushed equivelent:
3.5R (10,500kV) = 3-turn
4.5R (9,000kV) = 5-turn
5.5R (7,400kV) = 7-turn
6.5R (6,400kV) = 9-turn
7.5R (5,800kV) = 11-turn
8.5 / SS5800 (5,000kV) = 13-turn
10.5 / SS4300 (4,200kV) = 19-turn
13.5 (3,300kV) = stock 27-turn

Reedy Neo-One brushless / brushed equivelent:
4-Star (7,400kV) = 7-turn
3-Star (6,400kV) = 9-turn
2-Star (5,800kV) = 11-turn
1-Star (5,000kV) = 13-turn

* based on manufacturer-claimed specs

i have a bigger budget and i am trying to do a lot of research first so i can know most of the basics before i start. i am totally looking to just break into drifting and i dont think there is a drift club in my area so no races yet but definitely will once i slide my way threw my start (bad joke i know haha)

thanks!!!!!!!!!! for all the kv rating
i thought i heard that a BL motor needs more power and kills nimh batteries faster

yes there are higher T's available

ive got brushed 35, 45 and 55T's i use for rock crawling ..... and these are brushed motors which cost more than sensored brushless ones ....

Hi,

If you think you might ever race or drift with a club ask them if the specify any particular motor for competition.

In our races we use tamiya sport tuned 23 turn brushed motors and 13 turn hobby wing brushless motors. These are less powerful than most clubs use because we race tend to race two wheel drive cars.

For drifting competitions I am not sure if the guys specify a motor limit, if so I am sure someone will post shortly. As drifters are four wheel drive and you need enough power to break traction at will, you would need more power than our 2 wheel drive cars. So I am guessing a 19 turn brushed or 10.5 turn brushless would be a great starting point.

Drifters, what do you use and do you have a competition limit ?

Duane

drifting usually has open motor limits ... basically you can use what suits your driving style ....

Countersteer set-ups tend to use higher turn motors from 10.5 to 13.5 due to the motors thermalling caused by the rear wheels spinning faster ....

but yeah .... basically you can use whatever you want for drifting

very happy

If you have money, the best investment you could make would be to get some LiPo batteries, and a decent charger. If you learn about how to care for them, they would pay themselves of very quickly, and they perform waaay better than Nimh.

If you want a decent motor for drifting, I would recommend the hobbywing/yeah racing combos from rcmart. If looked after, you could use it for drifitng or car park bashing.

If you are going to race, then as mentioned before, check with your club, there will be limits for the differen classes.
