ROTOR FOR AN ELECTRIC MACHINE

The invention relates to a rotor for an electric machine (1). Said rotor (2) has a rotor member (4) extending circumferentially about the axis of rotation (R) of the rotor, and a locking device (6, 6') in an axial end region (11) of a guide (7a, 7b) in order to mount permanent magnets (5a, 5b) in the direction of the axis of rotation of the rotor, said locking device being retained on the rotor member (4) in the radial direction (F) and in the direction of rotation of the rotor by means of the guides. The locking device (6) has a movable movement element (9, 9') and is designed such that when the movement element is moved, the locking device is positively or non-positively connected to the rotor member. In the disclosed rotor for an electric machine, the permanent magnets are reliably retained on the rotor member of the rotor, and there is no need for bores extending through the rotor member to mount the permanent magnets on the rotor member.
