3D-printed rapid prototype rigs for surface mounted PM rotor controlled segment magnetisation and assembly

This paper examines the feasibility of dedicated 3-D printed rigs use for enabling effective build and magnetisation of PM segments and controlled PM rotor assembly of a surface mounted PM rotor design. To this end a commercial surface mounted PM rotor design has been rebuilt and modified to allow for representation of a range of different PM magnetisation conditions. It is shown that suitable geometry assembly rigs made of electrically and magnetically passive material can be rapidly prototyped using 3D printing and applied to enable efficient PM segment build and magnetisation in a desired layout, as well as controlled surface mounted PM rotor assembly.
