What are double or triple armature brushed motors ?
As the title may suggest what are double or triple armatures and what to they do ?
I understand about turns , high turns of fine wire = high torque low revs ,low turns thick wire = high revs low torque but I've never known what mechanically a double or triple armature is or its advantages .

If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.

Each wind is multistrand instead of a single solid wire. So rather that one say,16 gauge wire, a triple would have three 20 gauge wires wound at the same time, allowing you to pack more copper around the core, making hopefully a higher flux field and therefore more torque. That's the basics.

So it's a way to get high revs with better torque by having two or three strands of wire more efficiently filling the space , thanks .

I was always told the lower the wind the more torque a motor produced and the higher the wind more RPM (given the same turn)
I was old school - when old school wasn't cool !

I was told bitd the triples and quads (for example 16x4) were smoother; less brutal than a single or double with the same winds (ie 16x2).

Re: What are double or triple armature brushed motors ?
this is a very technical explanation, but very good at explaining the tradeoffs:
http://www.machinedesign.com/motorsdrives/how-calculate-new-dc-motor-parameters-modified-winding
essentially, you trade off torque for rpm for a given voltage. but the overall power (wattage) goes up as does temperature. this is why you need to gear down with a lower turn motor.

Here´s a good "cut out in cardboard" explanation.

Number of Turns
Refers to how many times the copper wire is wound around each pole of the armature. Basic guide:
More Turns (e.g. 19T) = Higher torque, less rpm, longer battery life. Slower but easier to drive.
Less Turns (e.g. 12T) = Less torque, more rpm, shorter battery life. Faster but more difficult to drive.
Number of Winds
Besides the number of turns, the number of winds refer to the number of wires wound around the armature. Basic guide:
Single Wind = Most bottom end power. Power is achieved at lower rpms. For short racing tracks with a lot of turns.
Double / Triple / Quad = Less bottom end power. Power is achieved at higher rpms. For long racing tracks with long straights.
Turns
Turns refers to the number of times the copper wire has actually been revolved around the armature. The higher the number of turns greater is the torque generated and hence greater is the power delivered. However that also means less RPM rating for your rc car electric motor. Generally less turns are preferred for making the rc car run faster.
Winds
One or more copper wires are usually wound around the armature. The number of wires that are wound around the armature is called the wind of the motor. Sometimes the wind is increased in order to compensate for the torque lost by reducing the turns.

Thanks guys it's clear in me head now
