właściwości elektryczne - Opis:
- The permanent magnets are used in basic consumer devices at home, in car or train. For example, these magnets may be found in electric motors and generators working in various environmental conditions. The permanent magnets have to meet the requirements of physical conditions, such as magnetic conditions, mechanical conditions, thermal conditions and electric conditions. These magnets should be also resistant to the environmental factors. In the article were presented the results of the measurements of the magnetic properties of: sintered ferrite permanent magnets, sintered magnets made from an alloy of Nd-Fe-B and SmCo and bonded magnets produced by bonding hard magnetic powder using a cohesive substance, so-called dielectromagnets. In case of sintered magnets the electric properties were additionally measured. Nowadays the sintered magnets are more and more often used in a construction of the electric motors. Their good physical properties and less expensive production technology of the magnetic circuits enables the designers of electric devices to construct the modern, low-energy electric motors. The lower costs of production enables to design the electric motor having better usable parameters. In the measurements were used the hard magnetic powders produced by Magnequench and Yuxiang.
