Abstract
The invention relates to a permanent magnet rotor, which has a rotor shaft, a rotor stack fixed on the rotor shaft, accommodating pockets provided in the rotor stack and permanent magnets positioned in the accommodating pockets. The accommodating pockets are sealed by means of an adhesive film, as a result of which the permanent magnets are fixed in the accommodating pockets and at the same time the ingress of particles into the accommodating pockets and the discharge of particles out of the accommodating pockets is prevented.
