Abstract

An electromagnet and method for producing an electromagnet. The electromagnet includes a sheet metal casing encompassing a magnetic coil at its end face on a magnetic pole side and extends into an interior of the magnetic coil and forms, in this case, a magnetic pole which interacts with a magnet keeper. The electromagnet enables actuation of a valve, a coupling or a reciprocating pump. The structure is achieved with as few cutting processes as possible to be used for generating the individual parts and as small a number as possible of individual parts is to be used per electromagnet.
