Magnetic linear actuators have a wide range of applications. Their main advantage is the ease with which they can be controlled by regulating the current. However, high electrical power is required for obtaining a large continuous force, acceleration, and stroke from a device with small dimensions. In this study, we developed a comprehensive open-source system consisting of simple movable iron magnetic actuators, a four-channel controller, and dedicated software. The graphical user interface facilitates the designing of the sequence of piston strokes, including the start time, duration of movement, and force for each stroke separately. The controller generates a high current of pulses, which allows achieving a high force, acceleration, and stroke from small-sized coils while maintaining a relatively safe voltage. The system was originally designed as a reagent syringe driver to control the rapid mixing process used for studying the kinetics of enzymatic reactions. However, this driver may also be applied in various other scientific as well as nonscientific applications.
磁性线性致动器有广泛的应用。它们的主要优点是通过调节电流就能轻松控制。然而，要从尺寸较小的设备获得较大的持续力、加速度和行程，就需要高电功率。在本研究中，我们开发了一个综合的开源系统，该系统由简单的可移动铁磁致动器、一个四通道控制器和专用软件组成。图形用户界面便于设计活塞冲程序列，包括每个冲程的开始时间、运动持续时间和力。控制器产生高电流脉冲，这使得在保持相对安全电压的同时，从小型线圈实现高力、加速度和行程成为可能。该系统最初设计为试剂注射器驱动器，用于控制研究酶促反应动力学时使用的快速混合过程。然而，这种驱动器也可应用于各种其他科学以及非科学应用中。
