An electromagnetic oscillating system is disclosed and includes an electromagnet with at least two poles. Each of the poles carry at least one electric excitation winding for connection to an alternating electric field. A rotor is disposed between the poles and includes a shaft that is rotatably disposed within the bore of the electromagnetic windings. The shaft is hollow and has a torsional spring disposed therein. One end of the torsional spring is rigidly attached within the shaft, while the other end extends from the shaft and is rigidly fixed to a stationary point.
