Abstract
An electrical machine includes a first active part and a second active part. Both the first active part and the second active part have a plurality of laminated sub-cores, with each laminated sub-core having a plurality of individual laminations. Each lamination is defined by an axial width. The laminated sub-cores are mutually spaced in an axial direction such that a respective radial cooling slot is formed between two adjacent laminated sub-cores. The radial cooling slots in the first active part are offset in the axial direction in relation to one another in comparison to the radial cooling slots in the second active part, and the sum of the axial widths of all individual laminations in the first active part corresponds to the sum of the axial widths of all individual laminations in the second active part.
