Work Platform and Practice of High Speed Magnetic Levitated Needle

结合新型磁悬浮驱动织针理论及模型,针对磁悬浮驱动机理及各种模型,设计实际应用的磁悬浮式织针驱动实践平台。基于模拟开关芯片和功放芯片架构驱动电路,设计在一个周期内的电流正反向驱动电路。结果表明,基于双通道的模拟开关芯片能驱动磁悬浮式织针,在一个周期内实现织针的高速成圈和浮线功位,织针高速编织往复动作可达到近20 Hz,同时输出驱动波形任意可调,可广泛应用于其他电路设计中。

Combined with the new magnetic levitated driven needle theory and model, and according to the various magnetic levitated incentive and driven models, the paper designs the actual application of magnetic levitated needle driven practice platform. Based on analog switch chip and power amplifier chip driven circuit, the positive and reverse drive circuit in one period is designed. The results show that the dual channel analog switch chip can drive magnetic levitated needle, and realize knitting and floating actions in one period, the high knitting action can reach more than 20 Hz, while the output waveform is adjustable, which can be widely applied to other circuit design.
