Abstract

PURPOSE: To reduce a cost and attain substantially the same shape and dimensions as those of conventional units, by using permanent magnets of ferrite and placing the magnets in separate positions on the inside surface of a housing.
CONSTITUTION: Permanent magnets 2 of ferrite are placed on the inside surface of an outer core 4. The magnetic flux of the magnets is efficiently concentrated toward the inner core 4 by pole pieces 12 made of a ferromagnetic substance. For example, three permanent magnets 2 are provided, discharge pipes 10 are laid through the gaps 13 between the magnets and fixation bolts 14 are extended through the gaps to secure the magnets. According to this constitution, the increase in the diameter of a compressor due to the placing of the permanent magnets 2 in an annular magnetic gap is substantially absorbed and the compressor is provided with the same shape and dimensions as those of conventional units.
