Abstract
Copper die casting motor (CDM) has a better design flexibility than aluminium die casting motor (ADM) because of the higher conductivity of copper. However, CDM has an economic and manufacturing weak point due to high copper price and high melting temperature compared to ADM. This paper describes a comparison of the design parameters, specifications, performances and material cost between CDM and ADM of 5.5kW_6P.
