  • construction of 3 phase motor work

    It is not surprising to find that this type of electric motor is so popular, when one considers its simplicity, reliability and low cost. In the last decade, it has become increasingly common practice to use 3-phase squirrel cage AC induction motors with variable voltage variable frequency (VVVF) converters for variable speed drive (VSD) applications.

  • Synchronous motor - construction and working - electricaleasy.com

    Working of synchronous motor The stator is wound for the similar number of poles as that of rotor, and fed with three phase AC supply. The 3 phase AC supply produces rotating magnetic field in stator. The rotor winding is fed with DC supply which magnetizes the rotor. Consider a two pole synchronous machine as shown in figure below.

  • How a 3 Phase AC Induction Motor Works - KEB

    3-phase AC induction motors are comprised of the stator and rotor. During operation, a current is applied through the stator, which induces a magnetic field and leads to the rotation of the rotor. The rotational speed of the shaft and the applied torque are dependent on the operating frequency and the number of pole pairs in the motor's windings.
