Integrated motor and controller for turbochargers, EGR valves and the like

An integrated motor and controller assembly for use with a feature of an internal combustion engine comprising, in combination,

• a housing,
• an electric drive motor disposed in said housing and having an output,
• a rotation sensing assembly on said output of said electric drive motor,
• a gear train disposed in said housing, operably coupled to said output of said drive motor and having an output member,
• a sensed assembly disposed for movement with said output member, said sensed assembly defining a plurality of distinctly sensed regions,
• at least one sensor disposed in sensing relationship with said sensed array, and
• a microcontroller operably coupled to said sensing assembly and said at least one sensor.
