Rotor assembly for electrical machine, has laminated plate stacks having positioning units positioned at axial end surfaces in juxtaposition at joining of two axially adjacent laminated plate stacks

摘要

The rotor assembly (100) has several laminated plate stacks (101,102) that are lined up in axial direction with respect to an axis of rotation (109) of the rotor assembly. The laminated plate stacks have positioning units (111-114) positioned at axial end surfaces (103-106) at predetermined angle of inclination (117) with respect to the axis of rotation for juxtapositioning and joining axially adjacent laminated plate stacks.
