传感器12与感应器次级控制电路9电气连接，传感器12感应到旋飞感应主体1的扭矩信号后，先通过感应器次级控制电路9接收，然后通过红外发射元件10和红外接收元件4进行数据传输，或者通过次级感应线圈7和初级感应线圈6进行数据传输；感应器初级控制电路3接收到信号后进行数据处理，然后将扭矩信号通过信号线8进行输出。
本申请提供的旋飞结构的动态扭矩感应装置的工作原理为：骑行时，用户通过登脚踏板带动脚踏盘转动，脚踏盘通过链条或皮带、旋飞等传动结构带动感应主体相对旋转部102转动，传感器12感测到旋飞感应主体相对旋转部102相对于旋飞感应主体相对固定部101之间位移大小或旋飞感应主体过渡部103的形变大小，再依次通过感应器次级控制电路9、感应器初级控制电路3转换为用户需要得到的脚踏的扭矩信号。
本申请实施例将旋飞结构的动态扭矩感应装置设计成一个模块化的装置，通过对旋飞感应主体的结构改进，使得旋飞感应主体过渡部103不受人体和整车的重量、链条拉力等外力的影响，从而可真实的反映脚踏的扭力大小，该装置结构更简单，同时可以装配到后置电机也可以装配到自行车的后花鼓上，通配性更强。
