1. A method of manufacturing an integral impeller and motor rotor, the method comprising:
manufacturing an impeller with a shroud;
modifying a radially outer surface of the shroud to prepare the radially outer surface for additive manufacturing;
additively manufacturing a motor rotor onto the radially outer surface of the shroud such that the motor rotor has a magnetic field with a geometry designed by computer modeling; and
magnetizing the motor rotor.
