Why is an insulation paper inserted during motor winding?


The conductor used during wiring is to be insulated from ground and each other as there is
potential difference among them. In general, after few turns of winding insulation paper is
inserted to avoid Inter-turn Breakdown.

Suppose the winding is of 200V having 1000 turns, this means the difference between 1st turn
and last turn will be about 1kV. So only Enameled insulation will not withstand this voltage.

Thats why paper insulation is used in winding.
