Experiment § Motors Magnet Bonding Adhesive

In electric vehicle motors, new energy vehicle drive systems, industrial motors, and precision electronic assemblies, the magnets (such as NdFeB and ferrite)on the rotor and stator must be securely bonded to metal substrates (Fig. 1). Insufficient bond strength may cause the magnets to loosen after prolonged exposure to high temperatures and vibrations, which can compromise motor performance. To address this issue, Everwide has developed a one-component epoxy adhesive specifically designed for motor magnet bonding. Unlike conventional anaerobic adhesives, this product requires heat curing. Once cured, the adhesive provides high bond strength, excellent heat resistance, and outstanding vibration resistance, making it ideal for mass production and automated syringe dispensing processes. A series of reliability tests demonstrated that, after curing and long-term oil immersion, the cured specimens retained over 90% of their original bond strength after 4,000 hours (Fig. 2 & 3); In addition, after 500 hours of volume resistivity testing at 160°C, the material maintained a volume resistivity of 10¹⁵ Ω·cm (Fig. 4 & 5). These results confirm the product's stable performance, making it suitable for applications involving high temperatures and prolonged exposure to oils and greases. If you are interested in this product, please feel free to contact us. — Author: Ms. Li-Ling, Liu

About Us § Upgrade IT Equipment and Implement All-Flash Storage

Everwide currently uses critical systems such as Digiwin ERP, KM (Knowledge Management), and EasyFlow (for leave requests and approval workflows), with all data stored on hard disk drives. The hardware warranty on our old equipment is nearing expiration. If a failure occurs, the data may be unrecoverable and at risk of being lost entirely. This would bring the company's entire computer system to a failure, making it impossible to submit leave requests or check ERP account entries. Extending the warranty comes at a steep cost, and with the company's data continuing to grow, our existing storage is nearly full and access speeds have slowed. For these reasons, we have introduced new equipment: the PowerStore 500T (Fig. 1). The new equipment provides a larger storage capacity and can automatically compress duplicate data. When multiple users access Digiwin ERP simultaneously, enter reports, or retrieve data, the new equipment can support stable read/write performance while managing all shared company files, ensuring smooth, lag-free daily operations. Compared to the previous setup of multiple physical hard drives, the new equipment integrates everything into a single unit, saving considerable server room space along with cooling and electricity costs (Fig. 2). Best of all, the built-in, AI-powered monitoring system automatically adjusts the speed of the system and allocates resources, greatly reducing the workload for IT personnel.

Knowledge § The Three Stages of Polymer Creep (1)

When a polymer is subjected to a long-term sustained load, its dimensions gradually change over time — this phenomenon is known as creep. In tensile mode, the polymer chains, initially coiled, begin to straighten out under load and slide past one another in the direction of the applied force. As this occurs, intermolecular forces increase (or crystallinity increases), and the entangled chains are drawn progressively tighter. These effects cause the rate of deformation to slow over time, making the material increasingly resistant to further deformation — as if it were hardening. This "strain hardening" behavior is characteristic of the early stage of polymer creep.

Living § My Daily Life as a Biracial Taiwanese-Vietnamese

I am a second-generation new immigrant of mixed Taiwanese and Vietnamese heritage. When you step into my home, you'll notice a unique rhythm pulsing through the air. My mother is Vietnamese, and my father is Taiwanese, so our household is like a "multi-channel" radio with Vietnamese, Mandarin, and Taiwanese blending together naturally. To me, having a cross-cultural identity has never been a label—it is a precious gift. Growing up with it meant mastering an additional language and developing a broader, more diverse perspective than many others have. In recent years, several of my Vietnamese relatives have come to work in Taiwan, strengthening my connection to my mother's hometown. For instance, my cousin has taught me the latest Vietnamese slang, and I have shared Taiwanese pop culture with her in return. Even without traveling abroad, I can continue to learn about Vietnamese culture through my family and stay emotionally connected to them. I am fairly fluent in spoken and listening Vietnamese, though I still need to work on my reading and writing. To communicate more deeply with my grandparents and relatives in Vietnam, I have made up my mind to master the language. Although the language's complex tones and accent marks are challenging, learning each new word gives me a great sense of accomplishment. I hope to keep improving through self-study and eventually earn a language proficiency certification. Beyond this pursuit of culture, my family's support has also been a source of strength. When I was 18, I often worked until late at night, and my mother would often argue with me because she was worried about my safety. At the time, I didn't fully understand her concerns. Later, with my father's guidance, I realized that her worries stemmed from a profound love. Now, I believe that identity is not defined by external labels, but rather grows from family support and the confidence we develop to face the world on our own terms. Going forward, I'll keep learning Vietnamese, not only to preserve my mother's cultural heritage, but also to bridge the distance between us and bring me closer to my faraway family. — Author: Mr. Chia-He, Hsu
