Abstract
A rotating machine includes a machine housing defining a housing interior, a shaft disposed in the housing interior, with the shaft having a length and an axis extending along the length. The shaft is rotatable about the axis. The rotating machine also includes an impeller wheel disposed in the housing interior and coupled to and rotatable by the shaft, with the impeller wheel having an angular position with respect to the axis. The rotating machine further includes a backplate coupled to the machine housing and having a first side facing the impeller wheel, at least one target element coupled to and rotatable with the impeller wheel, a circuit board coupled to the first side of the backplate and facing the impeller wheel, and at least one sensor disposed on the circuit board for detecting the at least one target element to determine the angular position of the impeller wheel.
