About JAT
JAT - Jenaer Antriebstechnik GmbH develops and produces custom servo drives as well as complex mechatronic positioning and motion systems for high-precision tasks in the micro- and nanometer range. The portfolio includes multi-axis systems with ±1 µm path accuracy, linear axis systems with travel ranges of 100 to 2000 mm, rotary tables, rotary servo motors, linear motors, servo amplifiers, servo compact drives and stepper motors, as well as software and technology functions. Manufacturing is carried out entirely in-house at the Jena site on more than 2000 m² of production space, including cleanrooms of classes ISO 5 to ISO 8, with machining, sheet-metal and tube processing, welding, assembly and 3D printing for prototypes. Applications include electronics, laser technology, optics and optoelectronics, 3D printing, medical technology, semiconductor and microelectronics as well as mechanical engineering and research. JAT accompanies projects from consulting, design and simulation through prototype construction to series production and delivers worldwide.
