An axial flux machine 200 for operating in a subsea environment, the machine comprising a sealed housing 101 for containing a pressurised fluid, at least one stator 102, 103, and at a least one rotor 104 within the housing, and a pressure compensator 106 comprising a first fluid port 115 and a second fluid port 116. The first port is in fluid communication with an environment external to the housing and the second fluid port in fluid communication with the inside of the housing, the pressure compensator arranged to pressurise fluid inside the housing via the second fluid port in response to the fluid pressure at the first port. A fluid conduit 117 may be provided connecting the second port of the compensator with a fluid port of the housing. The compensator may be integrally formed with an end plate of the housing. The compensator may comprise a chamber comprising a first 112 and second part 113 separated by a moveable seal 114. The seal may be a piston or diaphragm. A resilient member 114 may apply force to the seal to generate additional pressure at the second fluid port where the member is a spring. Sensors may also be provided for pressure, oil condition, temperature and vibration. The housing fluid may be synthetic oil, distilled water or water-glycol.
