Abstract: 一种智能中轴、智能魔方及其计时方法。该智能中轴包括核心、传感器（300）和主控模块（410），核心包括具有空腔（101）的壳体（110）；传感器（300）安设于核心上，传感器（300）包括定子（310）和转子（320），定子（310）固定于壳体（110），转子（320）被配置为能与智能魔方的魔方层连接且同步转动，从而使得转子（320）能够随魔方层相对于定子（310）转动；主控模块（410）安装于空腔（101）内，主控模块（410）与传感器（300）电性连接，主控模块（410）根据转子（320）与定子（310）之间的相对转动，获取魔方层的转动信号。传感器（300）和核心形成一个整体，集成化高，避免考虑定子（310）与中心块（210）或中间连接块（510）之间复杂的装配关系。
