    摘要： The present invention relates to rotating equipment, and more specifically, to high efficiency rotating equipment which generates thrust through contra-rotating or produces electricity. The rotating equipment includes: a plurality of propeller modules (10, 20) including a plurality of blades (11, 21) installed inside along a circumferential direction; and a rotary module (40) which rotates the plurality of propeller modules (10, 20) or is rotated.

    摘要： The present invention relates to rotary devices, such as an electric motors and power generators, having dual and multiple air gaps. Disclosed is a rotary device characterized by comprising a rotor part, a stator part, an inner support part, and a housing part. The inner support part is coupled and fixed to the housing part. The stator part includes: an inner stator part which includes an inner iron core coupled and fixed to the inner support part, and an inner wire wound on the inner iron core; and an outer stator part which includes an outer iron core coupled and fixed to the inner circumferential surface of the housing part, and an outer wire wound on the outer iron core. The rotor part includes: a rotor-side magnetic force application part which has, on the inner circumferential side, the inner stator part and an inner air gap, and has, on the outer circumferential side, the outer stator part and an outer air gap; and a pair of end support parts installed at respective ends of the rotor-side magnetic force application part. At least one among the pair of end support parts is coupled and fixed to a rotary shaft which is rotatably installed in the housing part.
