  Three-phase AC motor winding The basics of AC motor windings are introduced in the "AC Motor Winding" courseware, and the windings of single-phase motors are introduced. The windings of three-phase AC motors are introduced in this courseware. Three-phase AC motor winding basic structure It is well known that both electromotive force induced in the three-phase AC motor produces and rotating magnetic field generated on the three-phase AC generator are from an important part of the motor or generator, that is, the windings. The basic requirement for three-phase AC motor windings is: The potential  waveform generated by the three-phase AC motor and the magnetic field of the three-phase AC motor must be close to a sine wave and achieve the required amplitude. The potential or magnetic field generated by the three-phase windings must be symmetrical, and the resistance and reactance of each winding should be balanced. The copper loss of the winding is small, and the same to the am...
