During the Alexanderson alternator, both equally the sphere winding and armature winding are stationary, and current is induced while in the armature by virtue of the switching magnetic reluctance from the rotor (that has no windings or existing carrying components).

It is really 47x17x14mm (od id wide) and it is metallic shielded on the entrance aspect and open about the back again simply because a canopy plate is accustomed to safe the bearing from the push finish shield.
Other alternators have other bearing setups. The back again bearing doesn't have just as much load because the front (no belt rigidity about the again) but nonetheless.... if you do not change it...... As they say while in the manuals, reverse treatment to re-assemble!
