應 用 簡 介 / Description
As humanity’s dream of space exploration continues to expand, advanced nations are racing to push the boundaries of aerospace technology. In Taiwan’s latest aerospace industry developments, a well-known academic research team has spun off a startup—Tensor Tech—focused on realizing the first independently developed “world’s smallest spherical motor for satellite attitude control.”
Every day in near-Earth space, satellites orbit our planet and provide a wide range of services such as GPS positioning and TV signal relays. These satellites carry the culmination of human technology, yet they operate in an extreme environment: without atmospheric protection, they are exposed to intense radiation and drastic temperature swings (often more than twice the day–night range of a desert). During launch, they also endure severe vibration that can cause physical damage. After deployment into orbit, every system must operate reliably—maintenance is rarely possible.
Tensor Tech’s independently developed spherical motor for satellite attitude control must not only withstand these harsh conditions and deliver stable performance, but also meet strict requirements for lightweight design and ultra-compact size, since launch costs are extremely high. “In space, survive—or die quietly.” There is almost no margin for error, and repairs are not easily achievable due to the high cost.
Through close collaboration and discussions between the Tensor Tech R&D team and the Cometech R&D team, we contributed our experience in developing and designing high-environment-tolerance hardware circuits—vibration-resistant, radiation-resistant, and extreme-temperature-resistant—and successfully completed the foundational circuit development. Combined with software and firmware consulting services, we helped build know-how, reduce trial-and-error time, and accelerate the product’s time-to-market. Finally, under the strict space and cost constraints of satellite systems, we continuously refined the design to achieve optimal miniaturization and lightweighting.
While supporting Tensor Tech’s startup team in realizing the first “world’s smallest spherical motor for satellite attitude control,” the Cometech team understood that what we carry is not merely responsibility, but a dream taking flight—the aerospace journey of the spherical motor, reaching for the vast and boundless universe.
