  • Modular segmented stator package with coupling web with free-fitting pin
    Patent number: 11870303
    Abstract: A segmented stator has a plurality of individual teeth (12) connected to one another in the direction of rotation. Each individual tooth (12) has a connecting portion (17) to produce a nonpositive mechanical connection with at least one directly adjacent individual tooth (12). The respective connecting portion (17) has a groove-shaped fastening contour (18, 18a, 19, 19a), at least on one connecting side (17a, 17b), facing toward the directly adjacent individual tooth (12). The fastening contour (18, 18a, 19, 19a) of an adjacent individual tooth (12) can be connected to its connecting portion (17), such that a nonpositive connection is produced which ensures a magnetic flux.
