Optimized magnet assembly algorithms for reduced rotor unbalance: New rotor balancing strategy by measuring the weight of each magnet and placing it according to an algorithm

摘要

Rotor balancing for electric motors is nowadays crucial, because it ensures low mechanical excited vibrations and a high product quality. In this paper, a simulative investigation of different algorithms for the selective assembly of rotors, to reduce the mechanical unbalance, is presented. In order to do so, existing manufacturing deviations in the magnets are used as balance weights. The investigated algorithms cover offline algorithms as base of comparison and online optimization algorithms.
