Problems solved by technology

However, the on-board excitation part needs continuous power supply during operation. Although the TR maglev train is equipped with a linear generator on the excitation pole, the power generation cannot meet the on-board demand when the speed is below 100km / h. Therefore, it is still necessary to set up a power supply rail beside the track to provide On-board power supply increases system cost and reduces system reliability

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of maglev, in particular to a maglev drive device for a linear double-fed motor and a maglev train system. Background technique [0002] Linear motor drive technology is widely used in transportation and other fields due to its advantages of large thrust, strong climbing ability and small turning radius, providing a new solution for urban rail transit, cargo transportation and port logistics. In particular, the levitation linear drive system composed of linear motor drive and magnetic levitation technology avoids the contact between the moving part and the track, can achieve higher operating speed and acceleration, and reduces system noise, which has attracted wide attention. The typical application is magnetic levitation train. [0003] The linear motors commonly used in current maglev trains include short-stator linear induction motors and long-stator linear synchronous motors. The short-stator linear in...
