Patent ID: 8896165

Claim:
A generator, comprising: a stator comprising a yoke having teeth therein and defining slots between the teeth for windings; a rotor, rotatable around the stator, with a plurality of permanent magnets; and a cooling pipe for carrying a fluid for dissipating heat, the cooling pipe formed as a meander and comprising axial first sections along a bottom surface of the slots such that the first sections are in contact with stator windings within the slots, and further comprising U-shaped second sections for interconnecting the first sections, the U-shaped second sections disposed at opposing axial ends of the stator and in contact with an inwardly facing surface of a finger plate disposed at opposing axial ends of the stator, each U-shaped second section comprising first and second leg segments each connected to an end of an interconnecting segment with a connection, and a spacer between each finger plate and the stator and extending radially outward from the U-shaped second section.
