Driving Principle of a Motor (1)

A motor is rotated by the repulsion/attraction between the magnet and the magnetic field generated when the current flows in the coil.
The motor is rotated using the repulsive force from the same magnetic poles and the attractive force from different magnetic poles.
Then, by controlling the current direction of the coil wound around the stator, the magnetic field of the stator is switched in order and the rotor (with permanent magnet) is rotated.
