1. A rotating machine comprising:
a machine housing defining a housing interior;
a shaft disposed in said housing interior, with said shaft having a length and an axis extending along said length, and with said shaft being rotatable about said axis;
an impeller wheel disposed in said housing interior and coupled to and rotatable by said shaft, with said impeller wheel having an angular position with respect to said axis;
a backplate coupled to said machine housing and having a first side facing said impeller wheel and a second side opposite said first side and facing away from said impeller wheel;
at least one target element coupled to and rotatable with said impeller wheel;
a circuit board coupled to said first side of said backplate and facing said impeller wheel;
at least one sensor disposed on said circuit board for detecting said at least one target element to determine said angular position of said impeller wheel; and
a rotor coupled to said shaft for rotating with said shaft;
wherein said backplate is disposed between said at least one target element and said rotor with respect to said axis.
