The invention relates to a claw pole generator comprising a claw pole rotor, two magnet wheel halves () which are mounted on a drive shaft () and are provided with claw-shaped magnet poles () that mesh with each other, and an annular closing member () located between adjacent magnet poles (). The magnet wheel halves () can be inserted into pockets () of the closing member () along with the magnet poles () thereof such that the closing member () overlaps the magnet poles () on the edge in at least some areas. Also disclosed is a closing member ().

Claw pole generator and closure body for a claw pole generator

Electrical machine, in particular an alternator for a motor vehicle, with a housing () and a rotor () that is supported, in the housing (), in a manner that allows it to rotate around a rotation axis (), the rotor having at least one rotor winding (), a plurality of claw poles () disposed circumferentially, whereby adjacent claw poles () have axial claw overlap Land permanent magnets () have axial magnet length L, whereby at least one permanent magnet () is located between every two adjacent claw poles () and is magnetized so as to suppress leakage flux between the claw poles (), wherein the following applies for the ratio of axial magnet length Lto axial claw overlap L: L/L&#x2267;0.81.
