Description

technical field [0001] The invention relates to a winding device for a superconducting wire, in particular to a winding control device for a magnet superconducting wire. Background technique [0002] MRI nuclear magnetic resonance imaging system is a high-tech large-scale medical equipment. To realize the high-field MRI system, the production of superconducting magnet is the key. In the process of developing the superconducting magnet system, the superconducting coil winding process directly affects the superconducting magnet. performance. If the superconducting wire produces mechanical displacement under the action of electromagnetic force, and the relative movement occurs between the turns, it is very likely that the conductor will be quenched or the temperature of the conductor will be overheated. Therefore, the winding of the magnet must be tight, the gap between layers and turns should be as small as possible, and evenly distributed. After winding, it should be filled ...

Problems solved by technology

Current tension control systems generally use magnetic powder clutches or torque motors as actuators, but using magnetic powder clutches as actuators has serious hysteresis, and it is difficult for torque motors to meet the working requirements of small torque and high speed or high torque and low speed.
