DARPA SBIR solicitation SB082-011 seeks the design and development of high power density electric motors for hybrid electric air platforms, indicating a need for a prototype motor rated at 7 hp, weight less than 1.4 lbs, efficiency greater than 95% and operating at speeds less than 10,000 revolutions per minute (RPM), to be used for a ducted fan of less than 12 inches in diameter with a targeted speed of 8,400 RPM. During Phase 1, D-STAR Engineering engaged in preliminary and analytical design and optimization of such a motor, labeled the TAG Motor, and indicated its feasibility. Upon invitation by DARPA, D-STAR has prepared a proposal for detailed mechanical design and development of a prototype for such a motor. Technical details of the TAG Motor are included in relevant sections of this proposal.
