High-temperature magnetic data plays a crucial role in the development of advanced technologies, especially in the field of new weapons and equipment. It is a key component in the core systems of modern power solutions, including high-energy integrated power supplies, built-in starter/generator units, and non-contact magnetic bearings. Currently, the operating temperature of integrated power supplies is limited to around 300°C. However, the second-generation electric space shuttle (MEAII), planned for operation by 2005, aims to function at temperatures between 500°C and 600°C. Researchers at the University of Texas Austin’s Electromechanical (UT-CEM) lab are developing a flywheel communication generator for pulse power supply systems used in next-generation hybrid electric combat vehicles. This system also supports propulsion and full active electromagnetic suspension systems. Induction traction motors require power supplies that can store up to 25 MJ at 20,000 rpm. Weapon systems with intermittent operations must deliver peak power of up to 5 MW and continuous power of up to 350 kW. High-speed starters operate at temperatures exceeding 400°C, with components designed to withstand stresses of up to 825 MPa. Core losses and air pump losses affect rotor performance, and high stress combined with elevated temperatures can cause deformation and creep in electromechanical parts. To address these challenges, high-speed starter/generator units are integrated into main propulsion engines, allowing operation in high-stress, high-temperature, air-cooled environments. These systems rely on advanced magnetic bearings to ensure smooth, frictionless operation. The U.S. military, NASA, and aerospace industries are all investing heavily in magnetic bearings, particularly those capable of functioning at high temperatures. They see potential applications in future gas turbine starters, integrated power supplies, and large main propulsion generators—where rotors are supported entirely by magnetic force, eliminating mechanical wear and friction. Permanent magnet bearings offer smaller designs compared to traditional soft magnetic bearings, but their operating temperature limits remain lower. Some radial bearings can operate above 550°C, and aerospace energy storage systems may function at extreme temperatures. In addition, flying control electromechanical systems and secondary power supplies also require high-temperature magnetic bearings to enhance performance. The U.S. military is actively developing high-energy weapons, aiming to replace conventional ordnance by 2030. Whether deployed on land, sea, or air, these systems demand high power and lightweight design. Advances in power attack, energy storage, and high-speed magnetic bearings, along with efficient cooling of electromechanical components, are critical to achieving this goal. Higher operating temperature magnetic materials significantly improve system efficiency and performance. As both military and civilian applications push the boundaries of mechanical and electrical systems, there is a growing need for power systems that can operate at higher speeds and temperatures. The development of advanced magnetic data series is essential for future technological progress. **Related Bearing Knowledge:** - Application of TIMKEN small shaft bearing dynamic laser marking machine on bearings - SKF imported bearings preloading intentions and methods to select the layout and functional characteristics of the five major types of bearings - SKF double row cylindrical roller bearing cage This article links to http:// Please indicate the bearing network http:// Previous: The terminology and definition of bearing torque, load and life number are as follows: The reason why KOYO bearing oscillates
