MAGNETIC ROTOR APPARATUS FOR A SIDE CHANNEL COMPRESSOR FOR A FUEL CELL SYSTEM, SIDE CHANNEL COMPRESSOR, AND A METHOD FOR MANUFACTURING A MAGNETIC ROTOR APPARATUS FOR A SIDE CHANNEL COMPRESSOR FOR A FUEL CELL SYSTEM

원문 (중국어)

The invention relates to a magnetic rotor apparatus () for a side channel compressor () for a fuel cell system () for conveying and/or compacting a gaseous medium, in particular hydrogen, wherein the magnetic rotor apparatus () is supported in such a way that it can be rotated about the axis of rotation () and/or can be driven by means of a drive (). The magnetic rotor apparatus () comprises a compressor wheel () by means of which a gas flow can be produced, in particular in a compressor space (), a hub (), a locking ring () and at least one bearing (). According to the present invention, the hub () comprises a recess () that extends in an annular fashion around the axis of rotation (). In this case, the components of the locking ring () and at least two segment magnets (), ideally four segment magnets (), are located at least almost completely in the recess (). The invention further relates to a side channel compressor () having a magnetic rotor apparatus () according to the invention and/or a fuel cell system () and/or a method for manufacturing the magnetic rotor apparatus ().
