Abstract

A phase displacement device (1) having a drive (2) with a drive shaft (4) and a transmission (5) for displacing the phase between a camshaft (9) and a crankshaft (12) is provided. The phase displacement device (1) has a sensor device (14, 15, 16, 17, 18, 19) with which the rotational speed or the position of a component (2, 3, 4, 5, 6) of the phase displacement device (1) is measured. In this way, a higher resolution is achieved with respect to the position of the camshaft.
