Turn, turn, turn...what does it mean exactly?

[dont slow down]

Brushed motors are very different than brushless motors but both have similarities. I will try to explain a brushless motor as best I can however I dont know quite as much about brushless motors as I do brushed motors.

Both types consist of: motor can, magnets, armature, and wire. A brushed motor also has brushes. Brushed motors have magnets fixed inside the can. The wire is wrapped around the armature which spins between the magnets. When power is sent to the motor, the brushes transfer the power to the commutator on the armature. The wire now has been energized creating a magnetic field opposite the magnets in the can thus forcing the arm to spin.

A brushless motor is similar but opposite. It still has magnets, wire, arm and can but no brushes or commutator. Instead of the armature having wire on it, it is a magnet armature and a very powerful magnet at that. The wire is wrapped in bunches inside the can. Power is sent from the speed control to the wires, energizing the wires in the can to create the magnetic field just like the armature in a brushed motor. The opposite magnetic fields force the armature to spin. As far as brushless motors being defined by turns I think it could go two ways. I think its just a rating to compare the brushless motor to a brushed one.

"Turn" ratings can be achieved two ways. (I'm just guessing on this part but it makes sense to me) Either A: more wire is inside the can therefore when it is energized it creates a stronger magnetic field causeing the arm to spin faster, or B: the speed control just puts out more power to the motor itself. Maybe someone else can shed more specific information on this?

passing current through a wire wrapped around part of the steel armature makes a magnetic field. current going one direction makes the motor go forward, current passing the other direction makes the motor go backward.
the current is passed through brushes to the spinning armature, which reverses the current, and attracts and repels the pieces of the armature to permanent magnets mounted in the motor's case.

Brushless motors mount the permanent magnets on the armature (still the spinning thing)
and mount the wound up wire to the motor's case (for an in-runner)
A special speed control with 3 wires switches the current in the fixed (non moving) coils making the motor run without brushes by attracting the permanent magnet on the armature to different magnetic poles in the winding..

On some brushless motors, it looks like the whole motor is moving, it is a close guess. One end of the motor that mounts to the chassis is fixed, and the coils are connected to it. The armature runs through the coils, and connects to the back of the motor case, and the permanent magnets are mounted to the outside of the case (like a brushed motor)
the difference is the whole case turns with the armature and the coils staying still unlike the moving coils and armature in a brushed motor.
this setup allows more torque to be produced from a smaller package.

but I still wonder about how winds are counted, and how they compare power/speed-wise to brushed if at all
