The working principle of the one-way pulley is similar to that of the one-way clutch gear on the starter, which has the function of one-way slip. The generator pulley can only rotate in the same direction to drive the rotor to rotate. On the contrary, the pulley will only idle!

Its function is to decouple the alternator from the front engine accessory belt drive train, because the alternator has the highest rotational moment of inertia in the front engine accessory belt drive train. This means that the generator one-way pulley is a V-belt and can only drive the alternator in one direction.
