Double wound motors - how to calculate turns

[Percymon]

Silly question, but when looking at motors i noticed that LRP do two ranges of motors where they quote the turns as 17X2 , 19X2, 21X2.

How does this affect turn rating when pairing up with an ESC - is a 21X2 a 21turn motor, a 10.5turn motor ?

I assume its 21turns, as otherwise some of their hotter motors (11x2) would be very hot indeed for brushed motors. I want to check before i buy the wrong thing !

Thanks in advance

A 21x2 turn motor is 2 wires wound round armature 21 times so its still a 21 turn motor. You will be fine with an esc that can cope with a 21turn motor doesnt matter if its a 21, 21x2, 21x3, or 21x4 etc

Thanks but does double winding make it better - i assume single wire winds are of thicker wire so overall 'electric field' is similar to thin wire double winds?

"Reckum An Naquorum"?

Wreck 'em and acquire 'em?

"Buyicus Moor Tamiyacus" you mean?

Sure, why not.

Single wind gives more torque.

Multiple winds add revs.

Thanks.
