How much portion of the pole is covered with shading coil or shading band in shaded pole motor?
Right Answer is:
1/3
SOLUTION
A 1/3rd portion of each pole core is surrounded by a copper strip forming a closed-loop called the shading band. When a single-phase AC supply is applied to the stator winding, due to the shading coil provided to the poles, a rotating magnetic field is generated.
