Development of a Contactless Brushless DC Actuator for Engine Management 2006-01-1596

The requirements on vehicle emission control are more and more demanding. In order to meet these emission control requirements, internal combustion engines need to be more and more efficient and so require new electronic engine management features. These innovative solutions on engine management are usually based on electrically actuated or regulated valves, pumps and turbines. We have developed Brushless DC (BLDC) actuator designs dedicated to high temperature engine environment on applications like Exhaust Gas Recirculation (EGR) valve or Variable Geometry Turbo (VGT). These actuators encompass a patented low cost design of BLDC motor, a reversible motion transformation, and a high temperature drive electronic. Additional optional features like fail-safe return spring, analog position sensor or clutch can also be added in the actuator. This presentation will show the detail of the patented BLDC structure with an integrated position encoder, the integration of all these sub-assemblies for each feature in different actuator embodiments and the benefits of such actuators in applications like electric EGR valves or VGT electrically actuated. This paper will also present the possibility to decrease the cost of the drive electronic by developing an application dedicated ASIC integrating a standard three phase BLDC drive and all the specific features necessary in an automotive application like LIN or CAN communication.
