Founded in 1938 · Headquarters: Iida, Japan
Who is Tamagawa Seiki and what does it make?
Tamagawa Seiki is a Japanese manufacturer of servo drive components and angle sensors, headquartered in Iida, in Nagano Prefecture. The company was founded in March 1938 and describes its activity as the manufacture of encoders, resolvers, gyroscopes, AC servo motors with drivers and controllers, stepper motors, synchro transmitters and LVDT transducers. The group also has a European subsidiary, Tamagawa Europe GmbH, with its address in Ulm, Germany.
For a maintenance engineer, a typical part is the contactless angle sensor. Singlsyn resolvers (models TSY1010–TSY1050) operate between -40 and +150 °C, while the brushless Smartsyn accept, in the built-in version, an operating temperature from -55 to +155 °C, and are used on electric vehicle motors, welding robots and injection moulding machines. The encoders carry the common name FA-CODER, in incremental and absolute versions, single-turn or multi-turn.
The TBL servo motor series covers formats from 14.5 mm housings (TBL-i mini, 3–40 W) to 220 mm (TBL-iIII, 500 W–4.9 kW), and the TAD88 series drivers have an alarm logging function. For Romania, the range is of interest for replacing resolvers and encoders in existing drives, where the code engraved on the sensor identifies the exact part.
What do we supply from the Tamagawa Seiki range?
| Product | Description |
|---|---|
| Singlsyn and Smartsyn Resolvers | Angle sensors with analogue output, of the VR type (Singlsyn, models TSY1010–TSY1050) or brushless (Smartsyn), with built-in or hollow-shaft versions, mounted on electric motors and industrial robots. |
| FA-CODER Encoders | A family of incremental and absolute rotary encoders, with single-turn and multi-turn or magnetic options, for measuring speed, angle and position in automation installations and laboratory equipment. |
| TBL Servo Motors | The TBL-i6 α, TBL-i6, TBL-iIV, TBL-iIII, TBL-V and TBL-i mini series, with power from 3 W to 7.5 kW, chosen by format, power and type of position sensor, resolver or encoder. |
| Stepper Motors and Drivers | Two-phase and five-phase motors with dedicated drivers, for open-loop positioning without feedback, in a compact construction with high torque at low speeds. |
Why Tamagawa Seiki?
- Contactless Singlsyn and Smartsyn resolvers — no optical or electronic components in the sensor, so they withstand temperature, vibration and shock where an optical encoder fails
- Wide temperature range — from -55 to +155 °C on the built-in Smartsyn resolvers, useful on motors exposed to heat or severe cold
- TBL servo motors in several formats — from the TBL-i mini with a 14.5 mm housing to the 220 mm TBL-iIII, so the same builder covers small and large axes
- 23-bit absolute encoders on the TBL-i6 α series — with a battery-free version for absolute position
- TAD88 series drivers with alarm recorder — a stop is diagnosed from the data saved at the moment of tripping

How do we supply Tamagawa Seiki in Romania?
We offer Tamagawa Seiki resolvers, encoders and servo motors to order. The lead time to order is typically 1–4 weeks, and for special configurations it may be longer and is stated in the quotation. For a resolver, send us the code engraved on the housing or on the stator (for example TSY1030), the outer diameter and the number of poles. For a servo motor, the complete nameplate helps, plus the model of the driver in the cabinet. With this data we can request confirmation of the exact model before ordering.
Whether a local service network exists in Romania for Tamagawa Seiki products is confirmed in the quotation, and compatibility between older and recent series is established only from the datasheet of the model concerned.
Frequently asked questions about Tamagawa Seiki
What does Tamagawa Seiki produce?
The company from Iida (Nagano Prefecture), founded in 1938, makes encoders, resolvers, synchro transmitters, gyroscopes, TBL servo motors with drivers, stepper motors and inertial systems. For industrial maintenance, the resolvers and servo motors mounted in drives and robots matter first.
How do I identify a Tamagawa resolver to be replaced?
The code marked on the resolver, such as TSY1030 for Singlsyn, identifies the part reliably. If the marking has worn off, measure the outer diameter of the stator, the inner diameter, the thickness and the number of poles, then send us the data together with the model of the motor it is mounted on.
Can you bring TBL servo motors to Romania, and in what time?
Yes, to order. When the item is available locally or at the supplier, the lead time is 24–72 h; otherwise, to order, typically 1–4 weeks. For configurations with a special encoder or connector, the lead time may be longer and appears in the written quotation.
Is a Tamagawa resolver compatible with my R/D converter?
It depends on the excitation frequency and voltage, the transformation ratio and the number of poles of the resolver. We state compatibility only once we have these values. Send us the data of the converter and of the old resolver, and we check the match before quoting.
What details should I give for a Tamagawa servo motor quotation?
The motor nameplate (TBL series, power, voltage), the type of position sensor, resolver or encoder, the shaft length and the model of the current driver. If the motor has a brake or gearbox, specify it. A photo of the nameplate helps with quick verification of the model.
How do I request a Tamagawa Seiki quotation?
Send the Tamagawa Seiki code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
