Abstract
A motor stator 400 is integrated with a position sensor 200 through a novel attachment ring 600. Electrical connection to the integrated device is through terminals 202, 210 that pass through the position sensor housing 250. The stator 400 is preferably overmolded, though other suitable forms of encapsulation are contemplated. The attachment ring 600 is preferably ultrasonically bonded to the sensor 200 during manufacture, prior to insertion of the motor armature 430. Other methods of attachment arc contemplated, and various types of motors and sensors are also contemplated.
