The innovation proposed for a self-bearing motor-generator (M-G) will achieve speeds above 30,000 rpm, moving the technology to a new frontier, not only for the motor but the generator functions as well. As applied to a flywheel energy storage system (FESS), the concept replaces the permanent-magnet bearings, conventional M-G, as well as the need for the active damper. The self-bearing function is implemented with a proportional integral derivative control and has adjustable damping as in conventional active magnetic bearings. As a result, the flywheel end rotors are shortened substantially and could enable running at much higher speed without concerns regarding the first bending critical speed. Further, elimination of rotor parts will enhance the reliability of the mechanical system. Although a self-bearing approach could result in a less efficient magnetic bearing combined with a less efficient motor, the proposed approach will solve the efficiency problem, making it ideal for the high energy efficiencies required for FESS. With such improved efficiencies and reliability, the self-bearing M-G will serve as a modular building-block technology for the power management and distribution systems used in observation platforms for earth science missions.","startYear":2004,"startMonth":1,"endYear":2004,"endMonth":7,"statusDescription":"Completed","principalInvestigators":[{"contactId":182792,"canUserEdit":false,"firstName":"Hsiang","lastName":"Ming Chen","fullName":"Hsiang Ming Chen","fullNameInverted":"Ming Chen, Hsiang","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
