Abstract
A single or composite lifting electromagnet has several cores whose poles can attract round, elongated or otherwise configurated ferromagnetic objects. The cores are surrounded by and/or flank discrete sensors in the form of Hall generators or induction coils which are provided in addition to exciting coils for the cores. The sensors are disposed centrally of or mirror symmetrically around the center of the electromagnet, and the purpose of the sensors is to generate signals in response to changes of the electromagnetic field to thereby facilitate automatic guidance of the electromagnet toward an optimum position with reference to an object which is to be lifted and transported, e.g., to the treating station of a machine tool.
