WebSo that means by using H-bridge one can both control the direction and the average voltage across the DC motor hence the speed. Reversing the polarity for an AC motor does not change its direction since there is no "polarity" in alternating current system. In an AC motor, stator windings create a rotating magnetic flux. WebJul 25, 2024 · The distinction has to do with fusing and switching. If a plug is wired correctly, turning off the switch will disconnect the hot wire. In addition, if the fan contains any sort of fuse or other such protection device, it will disconnect the hot wire when it opens.
