Further development of a pulse magentizer

- Abstract
- A machine for magnetizing permanent magnets is under development at LTH. The idea of the machine is to affect only small pieces of a magnet at the time to obtain magnets with an arbitrary flux density, of course with respect to the magnetic material. The final machine is supposed to work in a closed loop fashion. Every part of the magnet is magnetized, measured and magnetized again with a flux density based on the desired flux density and the measured magnetizing result until the final result is satisfactory. This thesis covers the development of a new control system for the machine including a new current controller for the coils providing the flux. It also includes performance tests of the magnetizing head and a parameter study of the... (More)
