Motor comparisons?
Posted: Fri Jan 02, 2009 10:51 pm
Is there any chart that shows the relative performance comparisons of varios turn motors? i.e. 11turn single vs 11turn quad and so on?
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.
