Abstract:
The presented innovative magnetic testing method utilises the fact, that each commercially available electromagnet can not only be used as an actuator, but also comprises internal sensor functions. This allows a huge application variety in the fields of non-destructive testing and condition monitoring of electromagnetic systems during production and within the application in the field. Each electromagnet, from the smallest relay to very fast acting injection valves and large electromagnetic brakes, can be employed as sensor for mechanic, electric and magnetic quantities. The obtained signals can be used e.g. for error detection, not only for internal mechanical issues inside of the electromagnet, but also for external errors occurring at the connected load.
