SIEB and MEYER

What SIEB and MEYER does

SIEB & MEYER AG is a German, family-owned industrial electronics manufacturer founded in 1962 in Lüneburg by engineers Reinhard Sieb and Johannes Meyer. The company develops and produces high-speed drive electronics, servo amplifiers, frequency converters, and CNC control systems, organized into three product families: Frequenzumrichter (frequency converters for high-speed motors including the SD4 and SD2 series with proprietary FPAM modulation), Servoverstärker (high-dynamic servo amplifiers such as SD2B plus, SD2S, and SD4S that double as control platforms for application software), and CNC-Steuerungen/Motion Controller (including CNC 95.00 and CNC 93.00 for PCB drilling and milling machines, the MC2 motion controller, PCD36, and the SM IIoT Connect module). Underlying technical capabilities span FPGA programming (VHDL), firmware development (Assembler, C/C++), power electronics analog and digital design, sensorless and sensor-based control of synchronous, asynchronous, and IPM motors, circuit simulation across electrical/thermal/mechanical domains, and in-house 3D mechanical construction and PCB layout. All development and production are carried out at the Lüneburg headquarters, with high manufacturing depth including own aluminum and sheet-metal mechanics manufacturing.

The company's go-to-market is sales-led, with dedicated teams for CNC control technology and drive electronics supported by wholly-owned sales and service subsidiaries in Taiwan (SIEB & MEYER Asia Co. Ltd., Taoyuan) and China (SIEB & MEYER (Shenzhen) Trading Co. Ltd.), plus official representation in the USA (Cincinnati, Ohio) and an extensive network of regional channel partners covering Germany, Benelux, Poland, Switzerland, France, Spain, Portugal, Turkey, the United Kingdom, North America, India, Japan, Taiwan, and South Korea. The company claims a world-leading position in CNC controls for PCB drilling and milling machines and serves use cases in high-speed milling, grinding, dressing, dental CAD/CAM, semiconductor wafer dicing, compressors, wastewater treatment, atomizers, HVAC, flywheel storage, ORC and exhaust gas expansion, polygon scanners, special machine construction, and automotive screwing applications. Revenue is generated predominantly through hardware sales with a customized solutions (Kundenspezifisch) stream built around project planning through series production; pricing is quotation-based and not publicly disclosed. The company remains 100% family-owned by descendants of the founders, with Markus Meyer (descendant of co-founder Johannes Meyer) serving as CEO, Torsten Blankenburg as CTO, and an active SIEB & MEYER Foundation formed in 2003.
