Default Motor terminology

Ok, so i thought i know motors, i might still. Higher number =slower, lower number =faster (mostly true).

And i know Single and Double have high torque, so what do Triple and Quad have?

If triple and quad aren't as "torquey" as single and double, why do people use em in cars?

Please help...

higher the turn number you generally get less rpm and more torque.

Lower the turn number you generally get higher rpm and less torque.
The torque loss is minimal and when you compare it to the rpm gained. Lower turn armature will be able to go faster if you gear it right. (For more torque when you compare it with the higher torque motors)

single means how many wires go around that many "turns"
Single usually uses fatter copper wire and give you lower end torque.
As you get more and smaller wires around the comm, the torque curve moves back to higher rpms...


I hope this helped

Ok...but what are "turns" as you say?

And also...what do you mean by gear it right? What's to gear?

Turn meas how many times they wrap the wire around the stack of the armature.

on 7 turn motor, they wrap the wire 7 times on each stack of the armature.

you gear the motor. You know those pinion and spur gears? they change the ratio. It transfers the motor's work output into the wheels. for stock motor on a touring car, usualy motor spins 7.5 or 8 times to turn the wheel over once

The arm has 3 parts with wire wound around it. A stock motor has one wire wrapped aorund each part 27 times. This would be a 27 turn Single.

A 10 double would have 2 wires wrapped around each part of the arm 10 times.

The less the wire used (less turns) the less the resistance so the more electricity can flow through the wire. Motor goes faster. Motor wears out quicker and needs more maintnence too because it us using more power to make more poweer. Run time goes down.

Like Super Steve said, less turns more RPM so you have to gear the motor lower (smaller Pinion) to get the same speed out of your car or truck. If you don't use the right smaller pinion, Up goes your new mod motor in smoke. If you geared your Stock 27 turn motor lower it would just be slow. A mod motor has more RPM so the car will go faster AND have more power.

Just because you have a single compared to a dbl or triple does'nt always = more torque the circular mill of wire determines that.

Seems like generally a single or double will be wound with a lot lower gauge wire than a triple or quad or quint. Ive never seen a single or double modified wound with say 24 gauge wire because what would be the point? Usually the torquey motors are low gauge, low wind singles or doubles and rpm motors are somewhat higher wind, higher gauge trips or quads.

Correct, you have to use thinner wire with triples, quads, etc. on an arm than you do with singles or doubles because there's only so much space on each pole of the arm(that's each of the 3 sections of the arm) to fit wire in, so to make a triple, quad, etc., you must use thinner wire. The reason why some people use those kinds of winds are twofold. 1. They tend to be a bit more efficient by a small margin, so if run time is an issue(& it still can be on rare occaisions) then a multi-wind may help give your car enough run time to finish a race strong, & 2. the powerband for those kinds of winds allow for a smoother power delivery, which can make a car easier to keep under control in poor traction conditions(so in a low-grip situation, a multi-wind could make your car easier to drive smoothly).....

I dissagree

For Example:

A Monster Stock (27x1) gets 22,000 RPM's and 60W Torque.

A Chameleon (19x1) gets 23,000+ yet it makes 129w torque

A D5 (11x1) gets 29,900 RPM and makes 137 Watts

Yeah, I forgot about the smoother power of a trip or quad or higher...good point

They use triples and quads in 1/12th and 1/10th pan cars were they don't need torque.

Isn't watt a unit for power not troque?

The only problem with you observation is that each of those motors are different. They use different brushes, some use bearings or bushings, and the D5 uses different shaped wire. So you can't use that as an example to disagree with his comment. Besides you are comparing apples to oranges. His comment applies to the same motor with different windings.

Yeah, I believe wattage is a measure of power, not sure if its what the motor makes or what it consumes though.

I beleive it is the total output of power the motor makes.
