Towards manufacturing of perfect magnets

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding


Abstract in Undetermined
The paper describes a magnetizing machine for producing permanent magnets of desired magnetization pattern by use of feedback control. This will in theory mean that an ideal magnetization pattern can be realized, what could be described as a perfect magnet. The machine is to be used for applications requiring high accuracy magnets in terms of the shape of the magnetized area. This is, for example, important for reducing cogging in electrical motors. Results of initial experiments involving use of the machine are presented. The functionality of the machine from a production standpoint and modifications of it that could be useful for mass production purposes, the properties of materials used for magnets, processes involved in manufacturing workpieces that are to be magnetized are discussed. Applications that can benefit from use of a machine of this type are compared with more traditional solutions.
