- Electrical insulation and durability
- Frictional losses when operating in liquids
- Rotor sleeve design for permanent magnet retention
- Operation of e+a rotors & stators immersed in liquid natural gas (LNG, -160 ° C) and liquid nitrogen (LN, -196 ° C)
- Testing of different materials for operation in cryogenic liquids
- New rotor manufacturing variant developed and successfully tested.
- Evaluation of increased power density in cryogenic liquids
Based on experience gained in the LNG and LN markets, e+a is now taking the next steps to develop and manufacture motor elements for operation in liquid hydrogen (LH2, -253 ° C). Test results still pending.
