ABSTRACT:
A vibration exciter has at least two axles disposed parallel to one another, as well as at least two imbalance masses, which are attached to one or more of the axles. The relative rotary position of the imbalance masses can be adjusted relative to one another by a rotary oscillating motor having a rotor shaft and a stator housing. The rotor shaft is an integral part of one of the axles, and the rotary position of the stator housing relative to the rotor shaft can be changed. The stator housing can be locked to the rotor shaft. The oscillating motor has a rotor shaft and a stator housing, between which working chambers are formed. The stator housing can rotate about the rotor shaft and can be locked relative to the rotor shaft.
