[QUOTE="adulbrich, post: 8375080, member: 661255"] [quote name='Jscoyne2']I never did learn what imp rise was. Got any good articles that are informative?[/QUOTE] When you apply A/C current to a coil in a magnetic gap, several things happen.. The coil heats up when current passes through it. This heat creates some resistance. The coil reacts to the constant magnetic field of the motor structure and moves one way or another. Back EMF is created when it reacts to the constant magnetic field. The type of enclosure also affects impedance rise. Ported has a lot, sealed doesn't. Some ported boxes have more than others. Ask [USER=630747]@FML[/USER]; who is suffering from this badly. [/QUOTE]
