【 摘 要 】

In this paper, an estimation method for the ageing factor of permanent magnets is proposed. It is based on a multi-scale model, which allows estimating the magnetic properties of permanent magnets, combined with the magnetic viscosity theory. Using this method, the necessary measurements can be drastically reduced. The results obtained are compared with measurements, with a satisfactory agreement.
