Title:
ROTOR FOR PERMANENT MAGNET GENERATOR FOR GAS TURBINE, METHOD OF PRODUCING THE ROTOR, GAS TURBINE, AND METHOD OF PRODUCING THE GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2007/072536
Kind Code:
A1
Abstract:
Disclosed are a rotor structure for a turbine and a compressor that are formed
on the same axis, a compressor and a turbine constructed from a permanent magnet
generator and formed on the same axis as a rotor shaft of the rotor structure, and
a rotor structure for the permanent magnet generator. In the permanent magnet
generator, a magnetic circular cylindrical body is inserted on the inner circumferential
side of a ring-like permanent magnet split in the axial direction, a non-magnetic
circular cylindrical body is shrink fitted on the outer circumference of a rotor
shaft processed to the same diameter as the ring-like permanent magnet and of
the ring-like permanent magnet, and the ring-like permanent magnet and the rotor
shaft are magnetically connected and integrated together by the non-magnetic
circular cylindrical body. The inner circumference of both end surfaces of the
shrink fitted non-magnetic circular cylindrical body is welded to the outer
periphery of the rotor shaft to connect them, thereby corrosive gas and liquid
are prevented from entering into the rotor.
