Toroidal Cores
Toroidal Cores
Excellent Industries produces Toroidal Cores in various dimensions. The strip wound cores or toroidal cores are manufactured from coils of CRGO electrical steel to yield closely controlled electro-magnetic characteristics and dimensional accuracy. The cores are stress-relief annealed in an inert atmosphere to restore the magnetic properties. Special care is taken in handling and packing in order to avoid damage to the toroidal cores. The various types of Toroidal Cores available are:
- Uncut, Non Impregnated
- Uncut Impregnated
- Uncut and resin
- Cut and Impregnated
Efficiency
Toroidal Cores are constructed of a continuously wound ribbon, there is virtually no air gap. The windings are evenly wrapped over the entire core allowing the transformer to operate at a higher flux density than in standard transformers. The magnetic flux of the windings is oriented in the same direction as the grain-oriented core, thus achieving very high electrical efficiencies. Efficiency is a measure of a transformer's ability to deliver the input power to the load.
