1. A cooling cage assembly for a rotary electric motor, comprising:
a cooling stator arrangement including a stator and cooling tiles mounted against and around an outer circumference of the stator, each cooling tile including an upper side, a lower side, and at least one channel extending from the upper side of the cooling tile to the lower side of the cooling tile;
a first plurality of fluidic bridges arranged on the upper side of the cooling tiles;
a second plurality of fluidic bridges arranged on the lower side of the cooling tiles;
a first cylindrical part fixedly mounted against a first side of the cooling stator arrangement; and
a second cylindrical part fixedly mounted against a second side of the cooling stator arrangement opposite the first side of the cooling stator arrangement;
wherein a serpentine flow path, for a cooling fluid, around the outer circumference of the stator is formed by the first plurality of fluidic bridges, the second plurality of fluidic bridges, and the channel of the cooling tiles; and
wherein each cooling tile is arranged as a stand-alone component removably assembled, individually and independently from each other cooling tile, against a corresponding tile-receiving surface of the outer circumference of the stator.
