NettetAC motors are simple because the alternating current does all the work. By sending the current through a stationary wire that surrounds a shaft, you create a varying magnetic field, which in turn rotates the shaft. Remember, AC electricity goes from “positive voltage” to 0 to “negative voltage” at double your frequency (Hz) every second.
