Automated magnet assembly for large PM synchronous machines with integrated permanent magnets

Abstract

The manufacturing of large synchronous motors and generators with integrated permanent magnets currently contains a large amount of manual processes as well for handling as assembly. Magnets have to be separated and prepared for insertion manually, bearing a high risk for injuries. Due to increasing batch sizes in industrial as well as in traction drive applications, the efficiency of these processes has to be examined and developed towards an automated assembly. The paper presents an approach for partially automated manufacturing of a wide portfolio of rotors for drives on a single assembly machine.
