The invention relates to a cylindrical driver based on memory alloy wire driving. The cylindrical driver comprises a support serving as a bearing structure, a spiral spring piece, a memory alloy wire, a tail end stator corresponding to the memory alloy wire, a transmission component, an encoder for output shaft detection and a corresponding control circuit. The invention further relates to a working method of the driver, so that the rotation of the driver is realized by electrifying and heating the memory alloy wire. The noise problem of a traditional driver is solved, the structure is simplified, a robot applying the driver has more opportunities to be developed into a micro and portable type, and a new thought is provided for development of the driver. 本发明涉及一种基于记忆合金丝驱动的圆柱状驱动器，包括作为承载结构的支架、螺旋弹簧片、记忆合金丝、对应所述控制记忆合金丝的末端定子、传动部件、输出轴检测用编码器以及相应的控制电路。本发明还涉及驱动器的工作方法，以通过通电加热记忆合金丝实现驱动器的旋转。本发明消除了传统驱动器的噪音问题，简化了结构，使应用该驱动器的机器人更有机会向着微小型、轻便型发展，为驱动器的发展提供了新思路。
