Tamagawa Seiki is a globally recognized Japanese manufacturer of high-precision motion control devices, with a rich history of developing components for demanding applications in aerospace, defense, and industrial automation. A resolver is an analog angular position sensor that converts rotational position into a precise electrical signal. Unlike digital encoders, resolvers are known for their extreme durability and reliability in harsh environmental conditions.
Tamagawa Resolver Categories
Tamagawa offers a diverse portfolio of resolvers, each designed for specific performance and environmental requirements. Their main product lines are:
- Smartsyn® Brushless Resolvers: The Smartsyn series is a key product line known for its high resistance to shock, vibration, and extreme temperatures (from -55°C to +155°C). They are an ideal choice for high-speed motors in hybrid/electric vehicles, robotics, and machine tools. The brushless design ensures a long service life and is maintenance-free.
- Singlsyn® VR Type Resolvers: The Singlsyn series is a super-thin and compact resolver that has achieved a high level of reliability and reduced cost by eliminating the need for coils on the rotor. This design makes them highly robust and suitable for applications where space is at a premium and durability is essential, such as in factory automation equipment.
- FA-SOLVER® Brushless Resolvers: A series of brushless resolvers that are highly resistant to demanding environments. They are specifically designed for applications where long-distance transmission is required without degradation from electrical noise, making them ideal for large-scale industrial machinery.
Key Features
Tamagawa resolvers are highly valued for the following characteristics:
- Extreme Environmental Resistance: Their primary advantage over other sensors like encoders is their immunity to dust, moisture, vibration (up to 20G), shock (up to 100G), and a wide range of temperatures. They operate reliably where optical and electronic components might fail.
- High Reliability and Long Life: With a simple mechanical structure consisting of only an iron core and a coil, resolvers are robust and do not use electrical or optical parts. This brushless, non-contact design ensures a long operational life with virtually no maintenance.
- Analog Signal Output: A resolver outputs a sine and cosine signal that provides absolute position information within one electrical cycle. When paired with an R/D (Resolver-to-Digital) converter, this analog signal is transformed into a high-resolution digital position signal.
- Compact Design: Many of Tamagawa’s resolvers are designed as built-in types, allowing for direct integration into motor housings. This minimizes the overall system footprint and simplifies the final assembly.
