What is phase paper?
What will be an ideal response?
Phase paper is insulating paper added to the terminal leads that exit the motor. Inverter rated motors generally have phase paper added to the terminal leads. The high voltage spikes affect the beginning lead of a coil much more than the wire inside the coil. The coil is an inductor that naturally opposes a change of current. Most of the insulation stress caused by high voltage spikes occurs at the beginning of a winding.
