Patent ID: 8665043

Claim:
A rotor which comprises: a rotating body with alternating magnetization along the circumference, in particular along the enveloping surface, wherein a magnet ring ( 1 ) provided with alternating magnetizations (N, S) is mounted on a hub ( 2 ) through a connection device rotationally fixed and axially aligned relative to the rotation axis ( 10 ) of the hub ( 2 ), wherein the magnet ring is fixed by said connection device provided between an outer diameter of the hub and an inner diameter of the magnet ring, wherein an inner diameter of the connection device faces the outer diameter of the hub, and an outer diameter of the connection device faces the inner diameter of the magnet ring wherein the connection device is a friction locking element with elements which are spring elastic with respect to its radial thickness, in particular an annular circumferential friction locking band ( 3 ) made from flat stock, in particular with radial embossings, cutouts or bulges ( 4 ) and wherein the friction locking band ( 3 ) is a sheet metal strip with a plurality of bulges ( 4 ), subsequent to one another and offset from each other in circumferential direction, or of one or plural bulges connected to one another in cross section in cross section direction, which bulges continuously extend in longitudinal direction of the friction locking band ( 3 ).
