Abstract
A generator comprising a series of spaced annular stators sandwiched between a series of rotors, the rotors each being separated by annular collars, the annular collars defining a central cavity; at least one cooling gas source for supplying gas to the central cavity; vents through the annular collars for providing a means of egress for the cooling gas from the central cavity radially outwards over the rotors and the annular stators and the front, rear and side walls of coils embedded in the annular stators.
Claims21
A generator comprising:
- at least one annular stator having an inner circumference and an outer circumference and a plurality of spaced coils within and around an axis of the annular stator;
- and
- at least one cooling gap for the flow of cooling fluid in the annular stator between adjacent coils of the plurality of spaced coils, the at least one cooling gap having an inner opening in the inner circumference and an outer opening in the outer circumference, wherein the at least one cooling gap between adjacent coils of the plurality of coils accommodates a sealed channel for conveying the cooling fluid.
A generator comprising:
- at least one annular stator having an inner circumference and an outer circumference and a plurality of spaced coils within and around an axis of the annular stator;
- and
- at least one cooling gap for the flow of cooling fluid in the annular stator between adjacent coils of the plurality of spaced coils, the at least one cooling gap having an inner opening in the inner circumference and an outer opening in the outer circumference, wherein the at least one cooling gap between adjacent coils of the plurality of coils comprises two outer separate gaps at a radially outer end;
- and
- at least one accessible flow regulator for regulating the flow of cooling fluid through at least one of the at least one cooling gap.
