In case of using the lower energy density magnets, like ferrite or AlNiCo, there are still various possibilities to improve the magnetic flux density in the air-gap.
Alnico magnets were the first type of permanent magnets to be used for biomedical purposes.
Presently, Alnico is mostly used in applications where the ambient temperature is 250F or greater.
A proprietary seamless molding process seals the Alnico V magnetic core from solutions and possible leaching.
So-called permanent magnets are shaped or machined pieces of special materials, such as ceramic, Alnico alloy or rare earth materials, which have been magnetized through exposure to intense electrical fields.
Their AlNiCo magnets make these motors ideal for high-speed operation.
Each magnetic material, such as ceramic, samarium, neodymium or alnico, has its own reversible temperature loss.
The magnetic power source for Eriez' dual-wrap drum separator, Erium 3000, is a high quality rare-earth permanent magnetic material, which develops magnetic fields up to 25 times stronger than conventional ceramic or alnico magnets, with no increase in size.
These magnets have high-thermal-demagnetization coefficients compared with the traditional Alnico magnets, so they are not used in high-thermal-ambient conditions.
