A methodology for the design of fixtures for the multipole magnetization of axially magnetized permanent magnet rings is presented. The methodology, which is based on three-dimensional analytical field calculation techniques, embraces the calculation of the fixture electrical parameters, the electrical simulation of the fixture performance and the calculation of the level of saturation achieved in the permanent magnet. The methodology is validated by means of an experimental case study on a 6 pole isotropic NdFeB magnet ring.
