Rotor for an electric machine

摘要

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.

1. A rotor for an electric machine, comprising:
a rotor body configured for rotation about an axis and having recesses extending in a direction of the axis and forming guides; permanent magnets held by the guides on the rotor body in a radial direction and in a direction of rotation of the rotor body; and a plurality of locking fixtures arranged at an axial end region of the guides in one-to-one correspondence and held by the guides on the rotor body in the radial direction and in the direction of rotation, each said locking fixture having a movable moving element which when moved causes the locking fixture to connect with the rotor body by a positive fit or interference fit.
