To continue delivering the industry's most precise and reliable custom motor solutions, Kuo Shuay Motor has officially deployed a new-generation "fully automated motor inspection system and dedicated analysis software" in its in-house test laboratory. This upgrade significantly improves measurement precision and testing efficiency, while strengthening inspection capacity for high-efficiency motors, ensuring every motor shipped meets the strictest quality standards.

Precise Performance Measurement of PMSM Motors

In response to the industry's demand for peak efficiency and precise control, the new system offers fully automated measurement capability for permanent magnet synchronous motors (PMSM). Through a highly integrated hardware-software architecture and precision torque-sensing technology, we can rapidly and accurately capture operating parameters under various load conditions, providing a solid data foundation for the R&D and factory inspection of custom high-efficiency motors.

Full Compliance with the IEC 60034-2-3 VFD Testing Standard

In today's smart factories, pairing motors with variable frequency drives (VFD) has become standard. Our new inspection system fully complies with the latest IEC 60034-2-3 standard (specific test methods for losses and efficiency of converter-fed AC motors). This means we can move beyond traditional single-frequency testing limits and accurately evaluate the "real losses" and "energy efficiency" of motors when operating with a VFD, helping customers achieve optimal system-level energy savings in their end applications.

Continuous investment in advanced automated inspection technology is our absolute commitment to quality. We will keep building the most competitive motor products for global customers, backed by rigorous scientific data and deep R&D expertise.
