A magnetic levitation power device is revealed. The magnetic levitation power device includes at least two sets of power devices, a motor, and a power generator. The magnetic levitation power device features on the power devices each of which consists of a first seat, a second seat and a transmission set. A first sleeve is set on the first seat and a second sleeve is arranged at the second seat. The transmission set is composed of a shaft, a large gear and a small gear. Each of two ends of the shaft are disposed with two magnetic bodies respectively and are mounted in a sleeve. The magnetic bodies are arranged with like poles repel each other so that the transmission set is suspended and friction coefficient of the shaft is reduced. Therefore high speed transmission is achieved by low power to get high power.
