If You're not heading to eliminate and swap the slip rings, it's essential to insert the rotor shaft to the same extension depth as the brushes are fastened and also have worn a certain portion from the slip rings.

An alternator is really an electrical generator that converts mechanical energy to electrical Electrical power in the form of alternating latest.[two] For factors of Value and simplicity, most alternators utilize a rotating magnetic industry having a stationary armature.[three] At times, a linear alternator or a rotating armature which has a stationary magnetic field is employed. In principle, any AC electrical generator could be known as an alternator, but ordinarily the term refers to little rotating equipment pushed by automotive and other interior combustion engines.

With all the belt taken out, spin the alternator. The pulley really should spin conveniently without any wobble or runout.
