GMW’s own Dr. Zhen Xu, Magnetic Instrumentation Scientist, will be giving a presentation on “In-Line Production Test Equipment for Crack Detection in Permanent Magnets and Magnet Blanks” during the Magnetics/Motor & Drive Systems Conference in Orlando, FL. Presentation will take place on Tuesday, February 11 at 3:30 pm.
The quality control of permanent magnets in automotive and consumer electronics industries increasingly requires a reliable detection of mechanical faults in magnets and magnet blanks, such as cracks and material inhomogeneity. Such 100% production tests require in-line equipment that allow an accurate positioning of measurement probes with respect to the tested object, a reliable crack detection method and a high level of automation, which insures reliable test results within the shortest possible testing time. SENIS, with its Chinese system integrator MAS-Intelligent, achieved these goals by applying a non-destructive crack testing method with eddy-current probe arrays that are well positioned to scan all critical areas of different size magnet blanks. The precisely adjusted mechanical system in combination with the automation hardware and software modules, allows a seamless integration of the eddy-current probes and an accurate detection of cracks in the production line of one of the largest magnet suppliers.
