In industrial automation and highend equipment, standard motors cannot meet the demands of “extreme operating conditions” – from -196°C cryogenics to +200°C high temperatures, from 10⁻⁷ Pa ultrahigh vacuum to 8,000 m deepsea pressure, and from Zone 1/Zone 2 explosive gases to IIC hydrogen atmosphere
In extreme environments where liquid nitrogen boiling point (-196°C) coexists with ultrahigh vacuum (10⁻⁵ Pa to 10⁻⁷ Pa), standard motors fail: grease solidifies, insulation embrittles, seals leak, and metallic components may shrink unevenly. Motors that can operate reliably under this dual extreme
In deepsea exploration, underwater robotics, seabed mining and offshore oil & gas development, motors must operate for extended periods at depths of hundreds or thousands of metres. Seawater is both corrosive and conductive, with conductivity increasing under pressure, while every 10 m of depth adds
