The direction of alternating current keeps changing. How about the direction of AC motor?
The direction of rotation of the AC motor is not determined by AC + Half direction, but by the alternating current through the processing of a certain way to produce a rotating magnetic field acting on the rotor, as you hold a permanent magnet in the circle around the same compass compass as the principle of rotation make the rotor rotate, it the rotation direction depends on the direction of rotating field.
Three-phase motor to change the phase sequence (any two-phase electrical connection ~ ~ ~ ~ swap position)One way motor changes the direction of main winding or secondary winding in the direction of fire
There are many ways to generate rotating magnetic field, such as three-phase winding method, single-phase phase-shifting method, short-circuit loop method, pulse commutation method, and so on.
