Abstract

Electromagnetic vibration generator with an electromagnet composed of a U-shaped magnet core (3) with an excitation winding (4) which is cast in a housing (6) with casting resin (5), and of an armature (2) which is arranged with spacing as an air gap (D) in front of the pole faces (7) of the magnet core (3), the armature (2) oscillating in the air gap (D) with an oscillation width S in relation to the pole faces (7). In order to compensate the temperature-conditioned change in the width of the air gap, there is provision for the construction parts which act on the air gap (D) as a result of temperature changes to be constructed with respect to their constructional design, their arrangement and attachment in the oscillation exciter and their heat expansion in such a way that their influence on the width of the air gap (D) as a result of a temperature change is minimised. <IMAGE>
