Abstract: A multistage turbomachine (1) is disclosed, comprising a casing (3) with a fluid inlet (5) and a fluid outlet (7), and a plurality of stages (13A, 13B) arranged in the casing (3). A flow path extends from the fluid inlet (5) to the fluid outlet (7) through the sequentially arranged stages (13A, 13B). Each stage is comprised of a rotating impeller (17A, 17B) and an electric motor embedded in the casing (3) and arranged for rotating the impeller (17A, 17B) at a controlled rotary speed. Each electric motor comprises a motor rotor (31A, 31B), arranged on the impeller (17A, 17B) and integrally rotating therewith, and a motor stator (33A, 33B) stationarily arranged in the casing (3). Pairs of sequentially arranged impellers are configured for rotation in opposite directions.
