Abstract

A stator assembly (1) of an axial flux electrical machine is described. The stator assembly (1) includes a plurality of stator coils (4) and a plurality of core segments (2) arranged circumferentially to define a segmented stator core (3). Each core segment (2) includes a tooth part (2a) that extends axially and which is adapted to mount a respective stator coil (4). The stator core (3) can also be non-segmented with a plurality of tooth parts arranged circumferentially. Adjacent mounted stator coils (4) are spaced apart by a substantially trapezoidal void. The stator assembly (1) also includes a plurality of stator coil retainers (10). Each retainer (10) is received in a respective void between a pair of adjacent mounted stator coils (4) and its position in the radial direction is independently adjustable. Each retainer (10) includes at least one channel for receiving a cooling fluid (e.g., cooling air or a suitable cooling liquid such as water or propylene glycol). Each retainer (10) also includes a pair of contact surfaces that are spaced apart in the circumferential direction. Each retainer (10) is adapted to apply a contact pressure to the respective pair of adjacent mounted stator coils (4) through the contact surfaces.
