Drawing of rotating magnetic field in 3 phase induction motor

Production of a rotating magnetic field. The stator of an induction motor consists of a number of overlapping windings offset by an electrical angle of 120. For a three phase supply this can be done by interchanging any two of the three lines.

This video provides basic construction and working principle of three phase induction motor. We arrange the three phase winding in such a manner in the slots that they produce one rotating magnetic field when we switch on the three phase ac supply source. Thus it is necessary only to change the phase sequence in order to change the direction of rotation of the magnetic field.

Production of rotating magnetic field slip and rotor frequency is also discussed. As we shall see the rotor in a 3 phase induction motor runs in the same direction as the rotating magnetic field. So to act as an.

The stator of an induction motor consists of a number of overlapping windings offset by an electrical angle of 120. We saw in chapter 5 that when the induction motor is running at its normal speed the rotating magnetic field that produces the currents and torque on the rotor also induced balanced 3 phase induced e m f s in the stator windings the magnitude of the e m f s being not a great deal less than the voltage of the utility supply. Supply it establishes a rotating magnetic field which rotates at a synchronous speed.

A 3 phase induction motor derives its name from the fact that the rotor current is induced by the magnetic field instead of electrical connections. When the primary winding or stator is connected to a 3 phase a c. Rotating magnetic fields are often utilized for electromechanical applications such as induction motors and.
