A further paper clip or coat hanger wire bent into an "L" shape might help push the brushes down in the brush holder significantly enough To place inside the "retainer stick".
Typically you will discover three sets of stator windings, bodily offset so that the rotating magnetic area produces a three period existing, displaced by a person-3rd of a period of time with regard to one another. Synchronous speeds[edit]

A brushless alternator is made up of two alternators constructed conclude-to-end on 1 shaft. Smaller sized brushless alternators may seem like one device but the two elements are commonly identifiable on the large versions.
