| Abstract |
This paper presents an overview of the activity on
large Permanent Magnet Synchronous Machines (PMSM) in the
Nordic countries. It is found that the Nordic countries are in the
leading end of the development of large PMSM. This is much due
long traditions of ship building, an important application for
large PMSM, and pioneer work in wind conversion. The focus
has mainly been on the radial flux permanent magnet machines,
but in the later years also attentions has been given to axial and
transverse flux permanent magnet machines.
The industry has started to use large PMSM; e.g. ABB has
their compact azipod® with radial flux machine, Siemens has a
radial flux submarine motors and Jeumont uses axial flux
generator in wind turbines. The impression is that at the time,
the large machine manufacturers in Europe have radial flux
machines in their assortment and are developing the axial flux
technology. While the smaller and more specialised companies
have already developed axial flux machines for their
applications. |
