All three are synchronous electrical machines (except when they are not, i.e. there are also asynchronous AC servos or reluctance motors built as steppers). Steppers have a high pole-count and usually come is 2phase or 3phase variants whereas the non-stepper variants have a low pole-count and usually have three phases. Pole-count is the relation of electrical rotation to mechanical rotation, i.e. with 2 poles you need 2 full AC cycles for one mechanical rotation. The rest depends. _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
