1. An electrical machine having a rotor and a stator, the electrical machine comprising:
a plurality of electromagnetic modules having an electromagnetic material, the electromagnetic material being one of a permanent magnet or a stator winding, each of the electromagnetic modules comprising:
a base and a support extending from the base and supporting the electromagnetic material, the base comprising:
a bottom surface;
a first side surface and a second side surface, one or both of the first and second side surfaces comprising an axially extending open-sided groove;
wherein the open-sided groove mates with the open-sided groove of an adjacent electromagnetic module to define a closed-sided cooling channel; and
wherein the open-sided groove is configured for sliding receipt of a rod therein such that the stator segment is removable from an electrical machine by sliding along the rod.
