Power-Dense Electrical Rotating Machines for Propulsion and Power Generation

Under a Phase II effort, CS and Purdue will improve and validate the Asymmetric Permanent Magnet Synchronous Machine (APMSM) and Trapped Flux Coreless Machine (TFCM) design concepts developed in Phase I through development, fabrication, and testing of a hardware prototype of both technologies. The CS laboratory in Portland, Oregon and the Purdue University laboratories in West Lafayette, Indiana have capabilities for electromagnetic component (motors and inductors) fabrication, printed circuit board fabrication, and 4-quadrant dynamometer testing up to 130kW. As appropriate, CS will mount hardware prototypes to environmental test fixtures to begin the process of elevating the technology readiness of conceptual machines. The in-house CS laboratory environmental testing capabilities include ambient temperature control, humidity control, water submersion, and dust circulation. In addition to laboratory capabilities, CS and Purdue have experience procuring motor-grade magnets, high-strength 3D printed parts, machined metal parts, high power electronics, and MIL-SPEC connectors. Between the in-house facilities and industry contacts, CS and Purdue will be able to successfully design, fabricate, and test both machine concepts in Phase II.
