Abstract:
An electric multi-mode drive system (400), a method for operating the same, a vehicle (110) and a track (401). The system is arranged for operating at one part (402) of the track (401), at a station (410; 411), an electric Linear Doubly Fed Motor, LDFM, (310) for launching the vehicle (110), and for operating at another part (403) of the track (401), between stations (410; 411), a further electric motor (320; 330; 340; 350), not an LDFM, arranged for at least one of accelerating, coasting and restarting movement of the vehicle (110) after launching. Electric power for operating the further electric motor (320; 330; 340; 350), is provided by an on-board rechargeable electrical energy storage device. With the LDFM (310), sufficient power is generated for accelerating the vehicle (110), and recharging the on-board electrical energy storage device during standstill, braking and/or launching.
