I recall the original poster mentioning a 4" muffin fan - these are generally 120 or 240 Vac shaded pole motors - no permanent magnets. Other posters have talked about smaller DC fans - these DO have permanent magnets. As I see it - both sides of the argument are right because they are talking about different things. dwayne Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 16 years of Engineering Innovation (1984 - 2000) * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Do NOT send unsolicited commercial email to this email address.
