The disclosed apparatus, system, and techniques described herein allow pole retention hardware of the electric motor to also function as a cooling manifold for removing heat generated by the electrical coils. A pole retainer apparatus can include a pole retainer for retaining a pole to a hub. The pole retainer can include a proximal end mounted on the hub and a distal end. The pole retainer can include a channel extending through the pole retainer from the proximal end of the pole retainer mounted on the hub to the distal end of the pole retainer. The apparatus can include a mount located at the distal end of the pole retainer and configured to retain the pole on the hub. The apparatus can include a fluid transfer duct connected to the mount. The cooling system can be employed on TORUS Axial Flux Permanent Magnet motors, and various other motor designs.
