Technical field [0001] The invention relates to a device for simulating a space weightless rotation, in particular to a frictionless air-floating space weightless rotation simulation device. Background technique [0002] Among the existing high-precision rotating devices for simulating spatial weightless rotation, one is mechanical friction type rotation, which causes a large friction loss between the shaft and the bearing, and the simulation accuracy of spatial weightless rotation is not high; the other is Although it is air-floating rotation, it is not driven by a non-contact torque motor. This device is an improvement over the previous one, but it cannot control the speed between the shaft and the bearing, and cannot set the initial motion state of the rotating device.
