Abstract

A method of manufacturing an integral impeller (116) and drive motor rotor (136). The method includes: a first step of manufacturing an impeller (116) with a shroud (132), a second step of modifying a radially outer surface of the shroud (132) to prepare the radially outer surface for additive manufacturing, a third step of additively manufacturing a drive motor rotor (136) onto said radially outer surface of the shroud (132) whereby the drive motor rotor (136) has a magnetic field being optimized via a computer model, and a further step of magnetizing the rotor (136).
