Ocean-Spanning Dedication: Overseas CEO Paulina Single-Handedly Conducts Extreme 150,000 RPM PMU System Test at Kexiang Bearings

A "Geek CEO's" Trip to China

For precision hardware that demands ultimate performance, bearings are the "heart." Paulina, a tech-savvy CEO, was not satisfied with written reports. She chose to personally bring her company's core PMU (Power Management Unit) prototype to Kexiang's factory alone. She hoped to verify the physical performance of the bearings under high-speed switching in the most direct way possible.

An Extreme Dialogue in the Lab: The Spark Between Bearings and Electronic Control

In Kexiang's precision lab, Ms. Paulina personally installed Kexiang's MR52ZZ series bearings into her power unit. She was not only concerned with the data but also with the "sound" and "feel" of the bearings during high-speed operation.
In-depth testing: At an extreme speed of 150,000 rpm, the temperature rise of the bearings driven by high-frequency pulsed current was only slightly higher than room temperature. Paulina personally observed with an oscilloscope and confirmed that Kexiang's anti-magnetic design successfully suppressed shaft voltage, ensuring the absolute purity of the PMU drive signal.

Efficiency First: A CEO's Perspective on Supply Chain Inspection

Visiting alone meant extremely efficient decision-making. In addition to technical joint debugging, Paulina independently reviewed Kexiang's IATF16949 quality traceability system. She highly recognized Kexiang's closed-loop management, where "part precision is measurable, controllable, and improvable." She stated: "At Kexiang, I saw a professional partner who can resonate with a fast-growing tech company like ours."

Conclusion: The Cornerstone of Technical Trust

Two days of on-site testing involved no pleasantries or formalities, only high-intensity technical exchanges and data benchmarking. At the end of the test, Ms. Paulina directly placed a mass production order on the spot. This absolute trust, built on personal technical verification, is the best testament to Kexiang's business philosophy of "products must be ultimate."harvey
