Abstract
A method of designing and manufacturing an electrical generator which has a specific target power output rating includes the steps of selecting one of a predetermined, standardized set of diameters for the rotor, stator and frame of the generator; and subsequently selecting the length of the generator stator core and one of several standardized number of stator coil slots based on the target power rating and voltage of the generator. The invention permits standardized generator components which are specific to the selected set of diameters to be used during assembly of the generator, instead of customized components, which results in reduced design and manufacturing costs per generator.
Claims20
A method of designing an electrical generator having an intended power output rating which uses many standardized, modular components, comprising:
- (a) selecting a standardized set of diameters for each of the rotor and stator of the generator, said standardized set of diameters being used for the design of other generators having different power outputs than the generator being designed as well;
- and
- (b) selecting the length of the stator core based on the intended power rating of the generator, whereby standardized generator components which are specific to the selected set of diameters may be used during assembly of the generator instead of components which are unique to a generator having a specific power rating, such standardization resulting in reduced design and manufacturing costs per generator.
