Abstract
A variable reluctance resolver with a stator assembly including a printed circuit board having a first surface and a second surface. A plurality of inductors coupled with the annular printed circuit board first surface, wherein the plurality of inductors are in electrical connection with a power source. The variable reluctance resolver also having a rotor including a body with a first surface and a second surface, an annular recess located in the rotor first surface. The annular recess including a radially inner surface and a radially outer surface, wherein the annular recess defines a width variable with angular position. The plurality of inductors are located at least partially within the annular recess and the rotor is operable to rotate relative to the stator assembly.
