Abstract
A cooling cage assembly for a rotary electric motor includes a cooling stator arrangement, and a first cylindrical part and a second cylindrical part fixedly mounted against respective opposite sides of the cooling stator arrangement. The cooling stator arrangement includes a stator and cooling tiles mounted against and around the outer circumference of the stator. Each cooling tile includes at least one channel extending from an upper side to a lower side of the cooling tile. The cooling cage assembly further includes a first plurality of fluidic bridges arranged on the upper side of the cooling tiles and a second plurality of fluidic bridges arranged on the lower side of the cooling tiles to form, together with the channel(s) of the cooling tiles, a serpentine flow path, for a cooling fluid, around the outer circumference of the stator.
