Permanent magnet rotor for an electric motor has a laminated yoke with radially aligned retaining overhangs extending in the yoke's axial direction

摘要

Retaining overhangs each have a recess (19) that extends in an axial direction and is limited in a permanent magnet rotor's (10) direction of circumference by retaining sections (21), which are pre-stressed to sit close to permanent magnets (18) in the rotor's lateral surface plane and to fix the magnets in retaining spaces. An independent claim is also included for a method for fitting permanent magnets on a permanent magnet rotor.
