NEMO - Neodymium Iron Motor

The NEMO project aimed at investigating the suitability of a new type of Neodymium Iron Boron (NdFeB) magnet for space application and the issues to be addressed in this context. Since small electric motors conventionally use permanent magnets as rotors, their material properties have a huge impact on motor performance.

Short Description

An electric motor making use of state-of-the-art Samarium Cobalt (SmCo) magnets was used as a simple demonstrator. The rotor of this electric motor was designed for the new type of NdFeB magnets. A comparison was made based on detailed analysis loops and tests.

The permanent magnets were assembled into the rotor of the demonstrator, one equipped with SmCo magnets (for benchmarking purposes) and the other with the new type of NdFeB magnets. Finally, the test results were compared with typical space requirements.
