ABSTRACT:
To facilitate assembly of an automotive alternator, the alternator housing (11) is separated into two axially split half-shells (11a, 11b), the dividing line (11c) preferably passing through the axis of the shaft (18) of the alternator. The alternator assembly is made by providing a subassembly including the shaft, electromagnetic rotor structure, bearings, and a disk element in which rectifier diodes are seated and which can also support holders in engagement with the slip rings and the voltage regulator. The stator is slipped around the subassembly, a fan wheel and pulley can be attached to the subassembly which is then placed into one half-shell. The bearings and the concentric elements are positioned in alignment by seats formed in the half-shell, and the axial alignment can be accurately checked, and if the alignment is found proper, the second half-shell is assembled thereover.
