Actuation systems / x-by-wire



Ring gears are one of the main components of the planetary gear set in the starter motor and are typically made from plastic. Within the increasing start-stop technology, gears need to be stronger and more durable to withstand more frequent stress.

Creating the ring gears from powder metal provides a lightweight, high-performing solution, which is more resistant to wear and can achieve tighter tolerances.
