BRUSHLESS MOTORS
Brushless motors operate quite differently than brushed motors, which you may be
used to (i.e. a starter motor).
A brushed motor can be quickly tested by applying voltage to the two terminals.
Brushless motors can be recognized by 3 wires. These 3 wires require a controller to
operate them and to turn on these 3 phases in a precise fashion similar to spark plugs
firing a 3-cylinder gas motor.
Applying a voltage directly to these phases will cause damage.
