Abstract: An electrical gear (1) is disclosed, configured for supply of electrical drive power to a machinery (2) to be rotated at high speed, such as a subsea motor /pump or a subsea motor/ compressor assembly, the electrical gear comprising a high input voltage AC-motor (4) having a low pole number, the AC-motor drivingly connected to a medium output voltage AC-generator (90) having inverted design, wherein in the AC-generator the field windings are supported on a rotor (92) which is journalled for rotation inside an outer stator (91) carrying a high number of magnet poles, the AC- motor is configured to run on high voltage alternating current at a first frequency, and the AC-generator is configured to deliver medium voltage alternating current at a second frequency, higher than said first frequency, to an AC-motor to be energized (3; 30) having a low pole number. A method of operating a subsea machinery at high rotational speed in accordance herewith is likewise disclosed.
