Abstract

The helium enclosed compressor uses a helium gas as a working gas, houses a compressor section and a motor section including a stator having coil ends and a stator within an enclosed vessel, and discharges the helium gas, which has been discharged into the enclosed vessel from a discharge port of the compressor section, to the outside of the enclosed vessel through the coil ends. A plurality of varnish-treated layers which becomes insulating films is formed on the surface of a coil which constitutes the coil ends. Thereby, a helium enclosed compressor capable of preventing insulation breakdown of the coil ends caused by corona discharge is obtained.
