In a world of 240,000 rpm, we bring design theory into reality.
Our company owns the high-performance testing device "Centorio 100," which can handle ultra-high-speed rotation tests of up to 240,000 rpm and high-precision evaluations in environments up to 250 °C. We conduct contract evaluations under various conditions, including verification tests for plastic and elastic deformation of electric vehicle (EV) motors, as well as destructive tests, durability tests, imbalance evaluations, and vacuum tests. We confirm the consistency between our customers' design calculations and actual measured behaviors, supporting the improvement of reliability.
