Abstract: A copper die casting motor (CDM) has better design flexibility than an aluminum die casting motor (ADM) because of the higher conductivity of copper. However, CDM has an economic and manufacturing weak point due to the high cost of copper and its high melting temperature compared to aluminium. This paper describes a comparison of the design parameters, specifications, performances and material cost between CDM and ADM of 2.2 kW_4P, 5.5 kW_4P, 7.5 kW_4P.

Keywords: High-efficiency, cost, copper, aluminum
