Koob Testsystems GmbH – Precision in Testing Technology and Manufacturing
Koob Testsystems GmbH, based in Grabfeld, Germany, develops cutting-edge testing and measurement systems for electric motor components. Our innovative solutions enable fast, high-resolution magnetic field analysis of rotors and stators – from R&D to high-throughput series production.
Core Competencies:
3D Magnetic Field Analysis: High-resolution measurement of magnetic field components (Bx, By, Bz) for detecting unbalance, skew angles, and pole symmetry issues.
Fast Test Cycles: Fully automated pass/fail evaluation in 8 seconds – ideal for inline applications with tight cycle times.
Flexible Deployment: Mobile workstations for prototyping and small series, as well as inline integration for mass production.
In-house Software Development: Custom software for automated test plan selection (via serial number scanning), data visualization, and trend analysis.
Extended Capabilities: Programmable external excitation, slip-ring contact solutions, and electrical measurements for comprehensive testing.
Our customers benefit from reduced scrap rates, improved process control, and long-term quality assurance. We also offer full-service engineering including special machine construction and system design.

In-house CNC Manufacturing:
Our modern CNC production facility complements our test systems with precise, high-quality mechanical components. Equipped with state-of-the-art 3-axis and 5-axis machining centers from Hermle and DMG MORI. We offer:
CNC Milling: Precision machining from prototypes to series volumes up to 10,000 parts/year
Automated Sawing: Efficient raw material processing based on part lists
CAM-Driven Workflow: Seamless integration of CAM software for accurate cost/time estimation and production efficiency
Industry Applications: Specialized in electronic housings, enclosures, and shielding components for industries such as electrical engineering, communications, food processing, and machinery
Our integrated manufacturing allows us to deliver tailor-made solutions with outstanding precision and quality – all from a single source.
