Hi,
I use brushless DC motors for my hobby things (planes, cars, helicopters). These motors have a special ESC which outputs a 3-phase AC current to the motor. These motors have stationary coils, and a rotary magnet array. The motors have an incredible torque for the size. I have, however, though of a brushless motor which runs on solely DC current, no electronics, no AC anywhere. A motor that can be ran solely by a battery with no fancy ESC to run the motor. Is it possible to make such motors - in theory, perhaps in practice?
PS! Brushless, and no ordinary DC motor with rotating coils.
