About Tamagawa Seiki

Tamagawa Seiki Co., Ltd. is a Japanese servo components manufacturer headquartered in Iida, Nagano, founded on 3 March 1938 to develop local industry in the Iida region. The company specialises in angular precision: resolvers and synchros that detect rotation angle, encoders, gyros and rate sensors, AC servomotors, drivers and controllers, and step motors. Its official site presents a vertical products map running from space to the deep sea, with products for aerospace and defence, hybrid and electric vehicles, industrial machinery, surveillance camera systems and inertial measurement units, including new standard and high-precision MEMS IMU models announced in 2025.

The head office and first plant in Iida handle design and manufacturing of aviation, space and defence products, and the group reports a consolidated workforce figure in its corporate data. For directory partners, Tamagawa Seiki is a long-established private Japanese specialist in the resolvers, encoders and servo components that provide position feedback for robots, vehicles and high-reliability control systems.

GlobleMatch Trust Signals

A directory that doesn’t sell stars. Trust Signals are built only from verifiable facts — never from anonymous ratings, and never for sale. There is no single hidden score.

Public information coverage	8 of 9 fields on the standard profile could be filled from public sources. This counts how much public information exists about the company — not how good the company is. The nine fields are listed in the methodology. Claiming the profile lets the company complete the remaining fields itself.
Last verified	9 November 2026 — facts on this profile were checked against the sources listed below. Profiles are re-checked on a published 90-day cycle; this date is never quietly refreshed.

Claim this profile to unlock response record, directory tenure and peer endorsements. The full methodology — what each signal measures and how it is calculated — is published in the Trust Signals methodology, including a change log.
