Abstract

This paper describes the design and experimental evaluation of two high efficiency interior permanent magnet (IPM) motors for use in a commercial transcritical CO2 (R-744) heat pump water heater (HPWH). Two IPM topologies, 36 slot 6 pole and 9 slot 6 pole, were selected, optimized, and prototyped using a common, flat bar interior permanent magnet rotor. The experimental analysis includes standard measurements of electrical machine quantities, and light load dynamometer tests. Initial measurements of the CO2 compressor and HPWH system performance with a stock line fed induction machine have been completed.
