Effect on Design
The effectiveness of insulative coatings in resisting interlaminar current flow depends on the pressure on the core lamination surfaces and on the surface charac- teristics. Therefore, for best performance, unduly high assembly pressures should be avoided. Likewise, designers should avoid making excessively high esti- mates of needed insulation resistance. This penalizes the design because of the reduced lamination factor resulting from heavier-than-needed surface coatings.
