    as most people know,the fewer Turns the more power.the biggest misconception is the Windings.more winds also means more power but more rotating mass on the armature producing more rpms but not as much torque.more torque is used to spin the heavier armature.

    Winds are the amount of wires that are wound around the armature.
    Turns are the # of times the wire is wound around the armature.

    an armature is an electric magnet when voltage is applied to it.Brushless motors have earth magnets on the shaft instead and have the electric magnets on the can.

    so the magnets are on the opposite part than on the other one.

    Ya, the amount of winds changes the acceleration curve. More winds equals more power at mid-top end speeds. Less winds equals more acceleration and power in low-end speeds. This is pretty basic and makes sense when you think about it because the more winds a motor has, the more wires it has and the harder it is to be put into motion. But as this rotating mass starts spinning fast, momentum keeps it going and spins it faster and faster yielding not to good acceleration but good top end speed. Low winds is just the opposite, because of the low number of wires, it is very easy to set into motion so acceleration is good but it does not have the momentum that the higher wind motors do so it lacks the top end speed.

    it is Not momentum that makes a motor with more winds more powerful.it is the fact that it can carry more amps through the wire.you are right about the other stuff.

    Question I have a 8t motor and the armature wire busted I also have a 11t armature that is new now is the motor going to work if I put the 11t arm. in the 8t can using the end bell from the 8t?

    the only difference between the 2 is the armature and winds i think.should work fine

    Well it worked for a while or I should say until smoke came bellowing from under the TC3, the armature from the 11x2 was messed up broken wire . Anyway looks like I'm gonna spend a few bucks on a new 8t armature.

    That TC3 is bullet proof, just decided to drop a 10t Reedy touring motor in it's place for the time being.
