WebJan 26, 2024 · Normally the wire would stop at that point and then flip back again, but if we use an ingenious, rotating connection called a commutator, we can make the current reverse every time the wire flips over, and that means the wire will keep rotating in the same direction for as long as the current keeps flowing. WebAug 11, 2024 · Basics of single-phase motor starting: A single phase motor connected to a single-phase supply will not rotate as the windings do not produce rotating magnetic field. For one half cycle of the AC waveform torque will be produced in one direction and then in the opposite direction for the next half cycle thereby cancelling out rotor torque.
WebJan 20, 2024 · When we use external force to make the motor rotate in a certain direction (such as clockwise rotation), then the single-phase AC motor rotor and the instantaneous rotation direction of the rotating magnetic field between the cut magnetic line of motion becomes smaller; rotor and counterclockwise rotation direction of the electromagnetic … Web20K views 1 year ago In this video I am going to tell you how to change direction on a single phase motor, it is very easy.
