Analysis of the relation between electro-magnetic parameters and permanent magnet machine structure

The values of the electro magnetic parameters of permanent magnet (PM) machines are difficult to obtain by tests or calculations due to the various structures and the field complexity. The relationship between the electro magnetic parameters and machine structures has been investigated using the electro magnetic field analysis. Then the results are illustrated with a set of curves and stored into the database, so the parameters can be directly loaded from the database for a specific motor structure. This method can not only reduce the program development cycle time, but also can design and analyze various machine structures. Thus the versatility of the program is increased. Furthermore, the method guarantees the precision of the parameters since they are calculated directly from the electro magnetic field method. The results of simulations and experiments show that the method can be used to quickly and accurately analyze and design PM machines.
