Abstract

A rotor for an electric machine has a rotor member extending circumferentially about the axis of rotation of the rotor, and a locking device in an axial end region of a guide to mount permanent magnets in the direction of the axis of rotation of the rotor. The locking device is retained on the rotor member in the radial direction and in the direction of rotation of the rotor by guides. The locking device has a movable movement element and is designed such that when the movement element is moved, the locking device is positively or non-positively connected to the rotor member.
