ABSTRACT OF THE DISCLOSURE In a magnetically levitated train, a non- contact type power collecting device utilizing the harmonics of reaction magnetic flux generated from levitation ground coils is provided for supplying required power to air-conditioning equipment, lighting equipment, etc. in the train. In such a device, a plurality of power-collecting induction coils are disposed on the train body opposite to the levitation ground coils, and the voltage induced in the power- collecting induction coils by the harmonic components of reaction magnetic flux generated from the levita- tion ground coils is applied to a power converter to supply required power to the air-conditioning equipment, lighting equipment, etc. According to the present invention, the individual power-collecting induction coils have different numbers of turns depending on the level of the voltage induced due to interlinkage of the space harmonics from the levitation ground coils with the power-collecting induction coils thereby to balance the weights of the individual power-collecting induction coils with their power collecting capabilities, so that power can be efficiently collected to be effectively supplied to the loads.
