Patent ID: 8884490

Claim:
A stator ( 132 ) or rotor for an electrodynamic machine, the stator ( 132 ) or rotor comprising: a plurality of stacked partly annular plate segments ( 110 ), the plate segments ( 110 ) are stacked in a way to constitute several partly annular plate segment blocks ( 134 ) which when assembled constitute the stator ( 132 ) or rotor, each plate segment ( 110 ) has an outer side ( 112 ), an inner side ( 114 ), and first and second mutually opposite end faces ( 168 ) and ( 118 ), the first end face ( 116 ) of each plate segment ( 110 ) has a connection element ( 126 ) being a protrusion ( 126 ), whereas the second end face ( 118 ) of each plate segment ( 110 ) has a complementary connection element ( 128 ) being a recess ( 129 ), at least one coil array ( 138 ) is affixed to each plate segment block ( 134 ), an annular housing ( 145 ) affixable to the plate segment blocks ( 134 ), the annular housing ( 145 ) is composed of housing segments ( 148 ), each housing segment ( 148 ) has an inside surface and comprises hook-like connection elements ( 150 ) and ( 152 ) to affix the housing segments ( 148 ) to each other, the hook-like connection elements ( 150 , 152 ) of adjacent housing segments ( 148 ) engage each other, in such a manner that the mutually engaging connection elements ( 150 , 152 ) defining apertures ( 153 ) to receive a clamping pin ( 164 ), and that inserting the clamping pins ( 164 ) into the passage apertures ( 153 ) entails reducing the inside diameter of the housing ( 145 ) and clamps the housing elements ( 148 ) radially by their inside surface against the outer side ( 112 ) of the plate segment blocks ( 134 ) whereupon the protrusion ( 127 ) and the recess ( 129 ) of adjacent plate segment blocks ( 134 ) geometrically interlock and assure accurate orientation and dimensional stability.
