WebThe working principle of shaded pole induction motor is simple, the main winding carries alternating current and produces magnetic flux in the stator coil. The same magnetic flux cut by the copper shaded band. Due to this, the emf will be induced in the copper band. This emf circulates the current. This current produces own magnetic flux in the ... WebThis means, for reversing the direction of the motor, we need to change the direction of the rotating magnetic field. This is achieved by changing the phase sequence of the three-phase supply. For example – if a three-phase induction motor rotates in the forward direction for the phase-sequence RYB as shown in figure 2.
