Magnetic imbalances/NVH Abnormalities | e-motorKoob Testsystems GmbHThe industry is highly focused on e-mobility so the future of transportation will no longer be reliant on fossil fuels. Due to increasing demands in relation to production quality and output volume caused by politics, environment and economy, manufacturers all around the globe are forced to use new technologies on their production sites to fulfill those requirements. This rapid change leads to new challenges which are precious keeping an eye on them. For anyone who is using or building electric motors one major concern is the appearance of magnetic imbalances and NVH abnormalities. If such problems aren’t detected in an early production state because they aren’t visible as a mechanical defect they cost a lot of money, efficiency, time and even product-safety not to mention field returns. Since the beginning Koob Testsystems is confronted with magnetizing failures, low quality bought-in parts, non-efficient magnetic designs and a lot of other versatile problems, so they decided to develop a system to measure the magnetic-field of rotors and stators which allows their customers to detect abnormalities within their rotors and/or stators within seconds. Koob’s testing mashines scan the magnetic field of any kind of rotor and print out the exact location of a failure. The products are cycle-time-optimized what allows to check 100% of the output volume. Koob Testsystems is a full-service provider that develops, constructs and builds its complete productrange in-house what leads to an unmatched flexibility and service level. The highly integratable solutions offer a wide range of usecases.Typical Usecases: Product /Design ValidationProduct ComparisonPrototyping Diagnosis Development Evaluation Random spot-checks Quality ManagementIncoming goods inspection Whether you are using a stand-alone workspace testing single rotors or implement a measuring system within your production line, you’ll get an appropriate solution. Furthermore, you are able to speed up your process using automatic golden sample comparison or even evaluate your magnetic design as far as comparing different development-steps.
