ABSTRACT:
The claw pole generator includes a drive shaft, two field spider halves (30.1, 30.2) mounted on the drive shaft, each of which include a disk-shaped plate (15) and claw-shaped magnetic pole elements (17) mounted on the disk-shaped plate (15), so that the magnetic pole elements (17) of each field spider half are engaged with each other, and a number of permanently magnetic pieces (27), each of which is arranged between adjacent magnetic pole elements (17). The disk-shaped plate (15) of at least one field spider half (13.1,13.2) is provided with a number of grooves (21), each of which extend in the plate (15) in a longitudinal direction of the drive shaft (5) and have an undercut (25). Each permanently magnetic piece (27) has a section which corresponds in shape to or which fits into one of the grooves (21), so that the permanently magnetic pieces (27) are insertable in respective grooves (21) and radially securable therein.
