Properties

Semi-processed high permeability grades have guaranteed superior magnetic properties compared with the standard semi-processed grades (see data sheet D30). We offer two categories:

 

As for the standard semi-processed grades, the high permeability grades need a final annealing treatment, carried out by the client after punching the laminations.

Advantages

The semi-processed high permeability grades allow core weight reduction and increased efficiency of motors and transformers. The improved efficiency achieved reduces machine operating costs and at the same time makes them more environmentally friendly.

Applications

Semi-processed high permeability grades are designed for motors, generators, transformers, converters and ballasts where higher efficiency is required.

Recommendations for use

M450P-50K AM FCE and M600P-65K AM FCE need no particular machine production process adjustments. The very high polarisation levels of M560XP-50K AM FCE and M700XP-65K AM FCE diagonal to the rolling direction can be exploited advantageously for ballasts and small transformers by adjusting the punching operation, preferably in the 45░ direction.

Magnetic properties

The very high permeability grades (XP) offer excellent performance at 45░, with J2500 up to 1.79 T. Deviating from the standard Epstein test, we guarantee for these grades the average values measured in all directions of the sheet plane. These values are representative of the real material behaviour in a rotating machine.

 

The magnetic properties given for the high permeability grades (P) refer to the standard Epstein test (mixture of L and T direction).

Coating properties

As with the standard grades, the high permeability grades are available non-insulated. However, these high permeability grades can be supplied with an organic or inorganic-organic coating to meet higher insulating requirements.
