Aircraft Products


Over the years Tamagawa Seiki has contributed greatly to the aircraft manufacturing industry through the development, manufacture and overhaul of aviation instruments and devices. We are determined to strengthen our presence further in the fields of actuators, aviation control devices and instruments.

RVDT Cluster

RVDT cluster is position angle rotation sensor unit, equipped with multiple RVDTs in the shell to realize redundancy. As a key component, these products are integrated into the flight Control Systems to monitor aircraft pitch, yaw and roll motion control.


This electric linear actuator is designed for landing gear system of single-engine turboprop aircraft and twin-Jet. Gear train reduces brushless motor output to amplify its torque, and then rotational motion converts to linear motion by ball-screw. In case of emergency, free-fall system allows landing gear to fall by the own weight by pilot’s manual lever operation.

DC Brushless Motor

Maintenance-free DC brushless motor is designed to lock aileron positions during cruise flight, that control aircraft roll motion.

Innovation, quality and efficiency paired with high resistance and durability.

Since its foundation Tamagawa has taken up the challenge of further improving angular precision for control equipment such as high-precision sensors, motors and gyros. We are determined to satisfy your requirements with our high quality products by improving our technologies continuously and also constantly developing and applying new technologies. We can look back on an extensive industry-proven track record in all our fields of application.

Tamagawa Europe supports you in finding the best solution for your case of application.
