The invention relates to a magnetic levitation driving device based on a linear doubly-fed motor and a magnetic levitation train system, the magnetic levitation driving device comprises a linear doubly-fed motor stator and a linear doubly-fed motor rotor, and the linear doubly-fed motor stator is connected with a traction substation through a feed cable; thrust generated by the linear doubly-fed motor is used for providing traction force in the horizontal direction, normal force generated by the linear doubly-fed motor stator and the linear doubly-fed motor rotor is used for providing suspension force in the vertical direction, and an energy storage structure for collecting and storing electric energy is further arranged on one side of the linear doubly-fed motor rotor. The electric energycomprises electric energy transmitted from the linear double-fed motor stator to the linear double-fed motor rotor in a non-contact manner. The maglev train system is driven by the maglev driving device. Compared with the prior art, normal force of the linear double-fed motor is used as suspension force to achieve rotor side suspension, meanwhile, the linear double-fed motor can transmit electricenergy to the rotor side in the running process, the system cost is reduced, and meanwhile the linear double-fed motor is safer and more reliable.
