An electric propulsion system for aircraft comprises a propulsion fan 26 and a plurality of electrical machines 2) connected at respective positions to an elongate driveshaft 17 which is coupled to the fan. At least one of the electrical machines is operable as a motor, and at least one is operable as a generator. In some embodiments, the machines are operable as both a motor and a generator. Preferably, the machines are mounted in a duct, where the fan lies at one end, and airflow passes down the duct.
