Abstract
A generator (10) comprising a series of spaced annular stators (15) sandwiched between a series of rotors (11), the rotors (11) each being separated by annular collars (16), the annular collars (16) defining a central cavity; at least one cooling gas source for supplying gas to the central cavity; vents (23,24,25,26,27,28,31,32,33,34,35) through the annular collars (16) for providing a means of egress for the cooling gas (20) from the central cavity radially outwards over the rotors (11) and the annular stators (15).
Claims11
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 a central shaft on which the rotors and annular collars are carried, wherein:
- the cooling gas source comprises one or more fans caused to rotate by an ancillary electric motor, and the one or more fans are mounted on the central shaft, wherein the diameter and/or number of vents through at least one of the annular collars is gradually increased the further away the at least one annular collar is from the cooling gas source.
