In\norder to reduce risk, a sub-scale 5kW multistage MGG was first built. This project will benefit MHK device developers by providing an MHK PTO that overcomes the reliability concerns of the mechanical gears and the sizing constraints of the direct-drive generators. 7.67:1 gear ratio magnetic gear with a measured peak torque of 1796 N-m", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/files/417/85Hz_1020RPM_%20VFD-TD.xlsx", "description": "Magnetic gear torque speed step change measurements at 1050 rpm", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "Stage 2 85Hz 1020RPM VFD-TD.xlsx"}, {"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/files/417/static_stage2%20%5BServo-drive%5D.xlsx", "description": "Static torque slip measurements", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "Static Stage 2 Test.xlsx"}], "identifier": "https://data.openei.org/submissions/8740", "issued": "2021-05-30T06:00:00Z", "keyword": ["CEC", "Hydrokinetic", "MGG", "MHK", "Marine", "PTO", "WEC", "data", "energy", "gear", "gear ratio", "generator", "magnetic gear", "magnetic gear generator", "measurement", "measurement data", "power", "prototype", "scaled", "static", "static test", "sub scale", "sub-scale", "subscale", "test", "torque", "torque slip"], "landingPage": "https://mhkdr.openei.org/submissions/417", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2026-07-30T06:00:05Z", "programCode": ["019:009"], "projectLead": "Erik Mauer", "projectNumber": "EE0008100", "projectTitle": "A Hermetically Sealed Magnetically Geared Marine Hydrokinetic Generator", "publisher": {"@type": "org:Organization", "name": "Portland State University"}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-126.3495,43.715216554200296],[-122.3825,43.715216554200296],[-122.3825,48.9596],[-126.3495,48.9596],[-126.3495,43.715216554200296]]]}", "title": "Stage 2 Sub-Scale Magnetic Gear"}
