WHY POLE SHOE HAS BEEN GIVEN A SPECIFIC SHAPE

So as you know, pole shoe has been given a specific shape, So why it is need for a specific shapoe? I will share two main problems of this scenario.


  1. Pole shoe enlarges the area of armature core to come across the flux and which is necessory to produce larger induced EMF. So to acheive this, pole shoe has been given a particular shape.
  2. And (for given a shape) It is necessory that  maximum area of the armature comes across the magnetic field produced by the field windings.
