Brushless DC motors have a unique back electromotive force waveform that makes them behave similar to brushless direct current (BDC) motors.
Lorentz's law of force states that when a current-carrying conductor is placed in a magnetic field, it is subjected to a force. As a result of the reaction force, the magnet will experience equal and opposite forces. In a brushless DC motor, the current carrying conductor is stationary while the permanent magnet is in motion.
