N48SH
Sintered Neodymium Iron Boron Magnet – High-Performance Solution for Precision Vibration Motors This N48SH sintered
Neodymium Iron Boron Magnet is engineered for superior magnetic strength and operational reliability in compact, high-efficiency applications. As a premium-grade rare earth
Magnet, it delivers exceptional performance in demanding environments where size, weight, and power efficiency are critical. Ideal for vibration motor integration, this magnet combines advanced material science with precision manufacturing to meet the evolving needs of modern electronics. Key Features: - Grade N48SH indicates high coercivity and maximum energy product, ensuring powerful magnetic output - Nickel plating provides corrosion resistance and surface durability - Trapezoidal geometry optimized for precise fit and mechanical stability in vibration motor assemblies - Consistent performance across temperature ranges typical in consumer and industrial devices Detailed Description: The N48SH neodymium magnet is manufactured using sintering technology, which enhances crystalline structure alignment for enhanced flux density and reduced demagnetization risk. Its elevated HcJ (intrinsic coercivity) makes it suitable for applications requiring resistance to external magnetic fields or thermal stress. Unlike standard NdFeB grades, the SH suffix denotes enhanced thermal stability—ideal for environments up to 150°C. The nickel coating not only protects against oxidation but also ensures compatibility with automated assembly processes common in mass production lines. This design choice supports long-term reliability in portable and wearable devices, where failure-free operation is essential. Application Scenarios: Engineers and manufacturers rely on this magnet for vibration feedback systems in smartphones, smartwatches, and gaming controllers. It’s also widely adopted in automotive haptic interfaces, such as electric vehicle gear shifters and driver alert modules. In industrial automation, its use in robotic joint actuators and precision motion control units underscores its versatility beyond consumer electronics. Whether integrated into compact motors for wearables or high-torque systems for robotics, the N48SH grade offers consistent magnetic behavior under dynamic loads. User Feedback: Users report improved tactile response in vibration motors due to the magnet's high remanence and stable field output. Engineers appreciate the ease of handling during assembly and the predictable performance over time compared to lower-grade alternatives. Many note that the trapezoidal shape allows better integration into existing motor housings without redesign, reducing prototyping costs and time-to-market. Frequently Asked Questions: What makes N48SH different from other NdFeB grades? N48SH offers a balance of high remanence (Br) and enhanced coercivity (Hcj), making it ideal for applications requiring both strong magnetic force and resistance to demagnetization under heat or opposing fields. Is this magnet suitable for outdoor use? Yes, when properly coated—as with the Ni finish—it resists moisture and environmental degradation, enabling reliable performance in humid or variable conditions. Can it be used in motors operating at high temperatures? Yes, the SH classification ensures functionality up to 150°C, making it suitable for automotive and industrial motor applications where thermal management is crucial. Why choose a trapezoidal shape? This geometry maximizes magnetic flux utilization within constrained spaces, improving torque efficiency while minimizing axial displacement in motor designs.
