The specific windings in a three-phase AC motor are mainly based on the following data:įor the motor with P pairs of magnetic poles, the number of magnetic poles is 2p. Its Insulation should be reliable, there is need for high mechanical strength, dissipate sink heat, and simple manufacture. The copper loss of the winding is small, and the same to the amount of copper. 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 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 basic requirement for three-phase AC motor windings is: 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. Three-phase AC motor winding basic structure The windings of three-phase AC motors are introduced in this courseware. The basics of AC motor windings are introduced in the "AC Motor Winding" courseware, and the windings of single-phase motors are introduced.
