Abstract
An example embedded encoder for an outrunner brushless motor is provided. An example motor includes a motor shaft, a stationary stator, a rotor coupled to the motor shaft and provided external to the stationary stator for rotating around the stationary stator to cause rotation of the motor shaft, and a faceplate coupled to the stationary stator that includes a cavity. The motor also includes an encoder embedded into the cavity of the faceplate that comprises a code wheel coupled to the motor shaft and a read head for providing an output indicative of an angular position of the code wheel. The faceplate provides alignment between the code wheel and the read head.
