Abstract (en)
[origin: WO2017032441A1] 1. Electromagnet 2. Outline 2.1 Task: The electromagnet, at least consisting of a magnet coil (2) wound onto a coil core (6), a housing (3), a pole core (4), an armature (5), an armature rod (16) and a yoke (7), should have a very low hysteresis of the force with a variable stroke at low manufacturing costs. 2.2 Solution: The coil core (6) is manufactured by jointly overmolding or overcasting the yoke (7), the pole core (4) and the core flange (14) with a plastic mass (8), wherein the axial intermediate space (10) between the yoke (7) and the pole core (4) is also filled with the plastic mass. 2.3 Use: Electromagnets of the described type are used for actuating fluid valves or couplings, preferentially in motor vehicles or in mobile working machines.
