Cut cores available
28 February 2001
Power Electronics / Power Management
Magnetics, a division of Spang & Co manufactures cut cores which it says is ideal for applications where low core loss is needed and core saturation is undesirable:
* Supermendur (50 Co/50 Fe) C and E cores offer up to 30% reduction in weight over conventional 3% silicon-iron core designs in power transformers at frequencies up to 1500 Hz.
* Permalloy 80 (80 Ni/20 Fe) C cores are ideal up to 25 kHz for output transformers of high frequency, high power inverters. Other uses are high power pulse transformers, high frequency inductors and low loss current transformers.
* Orthonol (50 Ni/50 Fe) C cores have core losses about half those of silicon-iron C cores of the same material thickness. Orthonol is especially suitable for power transformer operation at flux densities to 10 000 gauss and frequencies to 8 kHz.
* Amorphous alloy cores offer low losses to 100 kHz at flux densities comparable to 50 Ni/50 Fe cores.
