Claims14
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.
