The purpose of this paper is to describe how a minimisation of cogging torque is performed with respect to the non‐ideal manufacturing process, aiming at a robust design of the studied machine, focusing on magnetisation faults and the use of different qualities of the permanent magnet material.
The applied methodology is a combination of design of experiments and finite element analysis to minimise the cogging torque of the estimated machine. Different qualities of the permanent magnet material are investigated by a stochastic analysis.
A robust design of the machine is achieved, which is verified by a stochastic analysis. Furthermore, this analysis shows the strong influence of the magnet quality on the cogging torque.
This paper provides a method for a machine design which is robust against non‐ideal manufacturing and an approach to prove the use of a bad quality for a possible reduction of the fabrication costs.
This paper gives a close insight on how to investigate non‐ideal manufacturing and in particular its influence on the cogging torque.
