New NdFeB Grades and Assembly Techniques

Over recent years NdFeB has seen a significant increases in the performance of grades in terms of both energy and temperature capabilities. With advances in metallurgy and production techniques, it is now possible to have production parts in N52 (52 MGO with a maximum working temperature of 80°C) and N50M (50 MGO & with a maximum working temp of 100°C). Further work is being done in labs to create grades of N53 and N55 and as soon as these reach production standards MSS will offer them to customers. Using magnets with such high energy values creates other problems, such as safe handling and assembly. Again further development work has been done in this area to make the assembly of NdFeB easier. Now many smaller motors can be assembled onto the rotor and then magnetised with the appropriate fixtures in-situ.
