Here are some basic definitions to help sort out some of the options. Enjoy !
Turns - The number of times the wire is wrapped around the armature. If you decrease the turns, the motor becomes more efficient, can pull more current, has a higher RPM but with less torque. So in very basic terms, in your head you can remember that turns equates to RPM. But high RPM generally means low torque.
-The higher the number of turns, the lower the power of the motor but a higher RPM.
-The lower the number of turns, the higher the power of the motor but a lower RPM.
But this simple view of things can be changed slightly by the number of windings...
Winds - The number of wires that is used for each winding around the armature. For complicated reasons, electrons flow with less resistance on the surface of a conductor. (This is why good quality speaker wire always has "stranded" wire rather than a solid copper core. Conduction and Valence bands, Covalent bonding, blah blah blah) So if you replace a single large copper wire with several smaller ones, you have effectively increased the total surface area of the conductor and most likely dropped the overall weight of the motor. So the more winds, the more efficient the motor is in general terms.
So why not choose a 10 turn single? You could, but at the cost of lowered run time due to lowered resistance which equates to higher current draw.
