Electrical machine for use as three-phase generator to supply electricity to electrical system of motor vehicle, has pole cores with radial poles containing magnets that are divided, where magnets are magnetized in alternating direction

摘要

The machine (10) has an electromagnetic claw pole module (16a) with two claw pole disks with pole fingers (19) interlocking at an outer circumference, where the claw pole disks are axially arranged at a distance to each other. A permanent magnetic excitation module has circular magnetic pole cores (25) with radial poles, which contains permanent magnets that are uniformly divided over the circumference of the magnetic pole cores, where the permanent magnets are radially magnetized in an alternating direction.
