The present invention relates to an apparatus of generating momentum which drives an object. The present invention provides a momentum generating apparatus in which a pair of high temperature superconducting coils which are wound in different directions and have different superconducting properties are arranged in parallel and the same current flows in the pair of coils to be in a stable state where magnetic fields generated in the coils are cancelled and an asymmetric current is suddenly applied to the pair of coils through a switching operation to generate a magnetic field and an eddy current is induced in a plate due to the generated magnetic field and the plate is floated using a repulsive force between the magnetic field generated in the plate due to the eddy current and the magnetic field generated in the pair of coils, to instantaneously generate force using a small amount of superconducting coils.

A superconducting synchronous motor having a simple and stable structure is provided. The superconducting synchronous motor according to one embodiment of the present invention comprises: a rotary shaft; a rotation core mounted at the rotary shaft so as to be rotated by connecting with the rotary shaft; and hooked magnetic poles extending from one end of the rotation core in a longitudinal direction. Each of the hooked magnetic poles is composed of first and second inductors of a magnetic material alternately engaged with each other and a superconducting wire to be wound, and comprises a first superconducting field winding and a second superconducting field winding fixed closely at the other end of a first inductor rotation core and the other end of a second inductor rotation core, respectively. Each of the first superconducting field winding and the second superconducting field winding excites the first inductor and the second inductor to different poles.
