How to reverse an induction motor
WebSpeed is important to the rotating magnetic field of an AC motor. It is known as “ synchronous speed .”. This speed is calculated by dividing 120 times the frequency (F) by the number of poles (P). As an example, the synchronous speed for a 2-pole motor operated at 60 Hz is 3,600 RPM. As the number of poles increase, synchronous speed ... 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 ...
