This report covers the design, fabrication, testing, and evaluation of a 5-hp, ultra-high-speed UHS squirrel cage motor, which was built in accordance with the concepts and design requirements developed under this USAERDL program. The primary goal of the program was to prove the feasibility of building lightweight motors capable of operating at high frequencies and high speeds. The work resulted in a comprehensive method of performance prediction for squirrel cage induction motors up to a frequency of 3,500 cycles. It was concluded that a The use of high frequency and high speeds in the field of electric machinery will result in very small and lightweight machines. b. The performance of the UHS machine can be brought up to a standard where it can compete with commercial machines. c The mechanical problems connected with the high rotor speeds can be solved by proper design and selection of materials.
