Abstract (en)
[origin: EP1054138A2] The method involves alternately applying a capture current to two electromagnets (3,4) with amplitude regulated depending on detected approach of an armature (5) to at least one pole surface. A reference temperature is detected for the magnets and the armature is stimulated to resonant frequency by alternately supplying current to the electromagnets for normal temperature and applied to a defined pole surface, preferably on the closing side. If a low temperature level exists then one of the electromagn preferably the closing one, is supplied with a high current pulse.
