Compared to today's assembly concepts, the automated placement of excited permanent magnets allows cost savings amounting to more than 50 %. The high labor effort, which is unavoidable when mounting permanent magnets manually, can be saved with the shown technologies. In order to solve the problem of the time for fixing the magnet during the hardening process of glue, the use of magnetic energy provided by the mounted permanent magnets offers further potential. As a survey among 39 manufacturers of permanent excited machines shows that 20 % of the asked companies use automated assembly systems, almost all with non-magnetized permanent magnets. Since the magnetic field changes with each single magnet added to the rotor, the resulting process force differs from magnet to magnet. Therefore, the critical magnet arrangements, which lead to the highest magnetic forces, have to be known for the proper design and dimensioning of the assembly resources. Regarding today's available gripping technologies, neither vacuum suction pickers, mechanical claws nor classic magnetic grippers comply with the appearing requirements. In a newly developed permanent magnet gripper, the magnetic flux of two highly energetic NdFeB gripper magnets is used to realize strong adhesive forces.The magnetic flux is concentrated by a ferromagnetic part which bundles the magnetic field lines to the bottom gripping surface. In order to inverse the magnetic field of the gripper for releasing the magnet, the gripper magnets are pivotable. With this arrangement, adhesive forces from more than 130 N can be applied to an NdFeB-part via an area of 4 square centimeters. However, the additional magnetic flux from the gripper more than doubles the process forces. This requires the use of very rigid and strong robots. In the first example, the described gripper system is deployed for mounting NdFeB-cuboids on a large rotor for traction motors. The second system is designed for the manufacture of PM-rotors for servo drives.
