Electric Actuators for Turbochargers

Pierburg, an integral development partner and supplier of components and systems in the Rheinmetall Automotive competence pool, has developed a new generation of rotary and linear turbo actuators fitted for turbochargers with wastegate or variable turbine geometry (VTG). Thanks to its modular approach, it is made possible to implement individual customer requirements such as connector position or design, in a cost-effective way and with little input. In addition to the necessary force and torque specifications, the new actuators also provide improved operating times, allowing a higher number of cycles and reduced weight.


Low noise and a high number of cycles


The two and three-stage mechanisms offer up to 360° angularity and up to 15 mm stroke at the output end. This enables a larger operating range and extended options for various functions. The selection of the electric motors and the chosen design facilitate a constant quality of operation even at an ambient temperature of more than 160°C. Depending on customer requirements, a return mechanism such as a torsion spring can also be used. A sensor system then enables fully variable control of the actuator over the entire adjustment range. The sensors can also send the present position signals to the engine controller in analog or digital form, depending on the requirements.
