Title: SEGMENTED STATOR FOR AN ELECTRIC MOTOR OF THE INTERNAL ROTOR TYPE
Abstract:
The invention relates to a segmented stator (12) for an electric motor of the internal rotor type, which comprises a plurality of stator segments (13) which in each case have a yoke region (13a) in the form of a circular segment having at least one stator tooth (13b) projecting radially inwards from the yoke region (13a), and wherein the stator segments (13) are joined together to form a circular stator lamination set (24) and are surrounded by an annular stator support (26). A plurality of axial through openings (20) are provided on the stator (12) for introduction of fastening bolts (22) for securing the stator (12) on a support element, wherein the through openings (20) are formed radially between the stator lamination set (24) and the stator support (26).
