#CMT# #/CMT# The machine (10) has a claw pole rotor (14) comprising hybrid-excited electromagnetic and permanent magnetic claw pole modules (16a, 16b) arranged axially adjacent to each other on a rotor shaft (15). The module (16a) has a field coil (17) for electromagnetic excitation and the module (16b) has a permanent magnet ring (25) for permanent magnetic excitation. Each module has two axially spaced claw pole disks (18, 20) with pole fingers (19) interlocked in the outer periphery. The ring has an unipolar radial magnet directly connected to the rotor shaft over a forward conductance ring (26). #CMT#USE : #/CMT# Electric machine for use as a three-phase generator, for supplying electrical energy to an electrical system in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The power density of the electrical machine is increased, so that the electrical excitation is reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of an electric machine with a hybrid-excited claw pole rotor consisting of electromagnetic and permanent magnetic claw pole modules. 10 : Electric machine 14 : Claw pole rotor 15 : Rotor shaft 16a, 16b : Hybrid-excited electromagnetic and permanent magnetic claw pole modules 17 : Field coil 18, 20 : Axially spaced claw pole disks 19 : Pole finger 25 : Permanent magnet ring 26 : Forward conductance ring. |
