The invention belongs to the field of wireless lifting and particularly relates to a direct-driven elevator system. The direct-driven elevator system comprises rotors connected with a lift car frame and stators fixed to a shaft wall of an elevator, wherein the stators are arranged at two opposite sides of a fixed U type supporting assembly, the number of the rotors is two, the two rotors are arranged in a back-to-back mode, and the stator and the rotor on each side form a linear motor to form a bilateral motor. The direct-driven elevator system adopts a bilateral motor simple structure, the rotors use a rectangular pipe structure rotor frame in common, meanwhile, the power driving and the positioning guiding braking are arranged in the U type supporting assembly in a centralized mode, a bilateral hybrid excitation linear motor can also be used as a lift power source and a magnetic levitation guiding device as well, the overall arrangement is more reasonable, the movement component can be made to be lightest, the machining, the installation and the maintenance are all very convenient, the practical degree is high, and the electromagnetic compatibility is good.
