A7.3 - Measurement System for the Characterization of Magnetic Actuators on the base of Magnetic Stray Fields

J. Franke, M. Brela & U. Pellkofer
Common defects in electromagnetic actuators due to the manufacturing process are heterogeneous magnetic properties of the materials, cracks and defects in the magnetic materials and parasitic air gaps in and directly around the magnetic circuit. Considering the high cost pressure, test systems must be adapted to the increasing complexity of the components and be able to detect defects completly in-situ. For these requirements the novel and non-destructive measurement system is suitable to monitor and assure...
