Heat Magnetization Techniques for IPM Motors   Below you can see one of the devices Nihon Denji Sokki uses for heat magnetization testing. Results from this setup proved that we can heat the magnet embedded in a typical rotor to the magnetization point within 60 sec using inducted heat from the rotor.   Heat magnetization techniques will be just one of the topics that we will be presenting next week at the World Magnetic Conference during #coiltech2024. (Augsburg, 20/21 March 2024).   Our booth will be 3-E27.

Big shout out to Naoya Tomita for sharing his vision on how we can advance IPM rotor magnetization technologies on behalf of Nihon Denji Sokki today at #EDPC. We are also grateful to everyone who took the time to attend his speech. We hope you found the information we presented useful.   #electricvehiclesarethefuture #electricdrives #emobility #electricvehicle #researchanddevelopment #motors #IPMmotor #energy #sustainable #power #magnetizer #magnetism #magnetization #permanentmagnet #engineeringsolutions #japanbusiness

For more information on how heat magnetizing methods for high-performance neodymium magnets are contributing to the adoption #PMSM (permanent magnet synchronous motors) in applications such as automobile drive motors or industrial motors that require miniaturization and high output, please refer to the below paper by Dr Michitaka Hori .

Heat Magnetization Techniques for IPM Motors   In an attempt to address the well-known poor temperature characteristics of #neodymium magnets, Nihon Denji Sokki has been developing heat magnetization techniques that use high-frequency induction to warm the surface of a rotor and thereby lower the required flux current needed to magnetize the rotor’s embedded #permanentmagnet.   By driving high-frequency AC through coils like those shown below, the resultant induction will generate eddy currents on the rotor's surface. As this heats the rotor, the temperature of the embedded magnets will also rise allowing us to use a lower flux field to complete the magnetization process for the motor. We found heating the rotors to 100°C allowed us to reduce the required flux density by 40%.   Heat magnetization techniques will be just one of the topics that we will be presenting at the World Magnetic Conference during #coiltech2024.  (Augsburg, 20~21 March 2024).   Link: https://lnkd.in/gFbjyD-C Our booth will be 3-E27.

LGE's active load simulator (PHIL) together with NEO's test and measurement system enables state-of-the-art testing of electric vehicle inverters (high-precise motor emulation). https://lnkd.in/dStuT_iJ .... run sophisticated motor models within nanoseconds #LGE #NEOMesstechnik #ALE #MotorEmulation #BatteryEmulation #PHIL

Nihon Denji Sokki would like to introduce its new English-language magnetic field press website aimed at supporting the magnet production industry worldwide.   Link:  https://lnkd.in/gZQ2QQ34   We see an opportunity for disruption in this industry, as the production of high-performance magnets is currently dominated by labor-intensive two-step die-pressing systems. Our single-step reduced isostatic pressure molds have already made significant progress in response to market trends, realizing better controllability and higher levels of automation over the whole process.   Let us put our know-how to work for you in finding cutting-edge solutions for your use cases.   #neodymiums #MagneticInnovation #electricvehiclesarethefuture #emobility #electricdrives #electricvehicle #IPMmotor #IPMSM #motors #permanentmagnet #electricvehiclesarethefuture #researchanddevelopment #engineeringsolutions #japanbusiness

AmePower’s groundbreaking propulsion inverter technology has once again been proven a success, marking a significant milestone for Kinkisharyo International and LA Metro’s P2550 fleet. Our innovation and effective approach to problem-solving was evident in the successful execution of the Low-Speed Bump Test. Originally planned with a two-week timeframe, we efficiently completed and passed this initial test within an impressive 48 hours with no major problems and an outstanding propulsion performance. This achievement is just the beginning! AmePower is Overhauling 100 Propulsion Inverters along with providing 100 Line Filter Reactors, 50 High-Speed Circuit Breakers, 100 Brake Resistors, 100 Center Truck Speed Sensors, and 200 Motored Truck Speed Sensors, including reserves for each. This leap enhances LA's transportation experience, particularly as the city gears up for the upcoming Olympics. The synergy created through the collaboration and dedication of the Kinkisharyo team and LA Metro has been instrumental in achieving the outstanding success of this project. Together, we are re-shaping the future of transit solutions.

Electric motor materials, are there any alternatives to "rare" appearing❓ We all know that rare earth elements such as neodymium, dysprosium, and terbium are used to make permanent #magnets in motors🧲. As of 2023, 81% of the motors used in BEVs are of the permanent magnet type, indicating a high reliance on rare earth elements. Many companies are seeking alternative technologies using non-rare-earth magnet #motors. Tesla and BMW are the main drivers of such technologies, using induction and externally excited motors, respectively. With the demand for motors set to increase exponentially and no other potentially viable and commercially feasible #technologies, I believe the demand for #neodymium will continue to rise📈 in the near future, which may pose more challenges. #magnetism #magnetics #magnet #NdFeB #NdFeBmagnet #SinterdNdFeb #SmCo #AlNiCo #RareEarthMaterial #MagnetFactory #MagnetManufacturer #NdFeBmagnetFactory #radiation #magnetic

We are thrilled to announce a significant upgrade in our engine development and testing capabilities with the arrival on site of our latest investment in cutting-edge technology. Advanced Innovative Engineering has acquired two Froude Eddy current dyno systems to enhance our testing efficiency and flexibility further. But that's not all. We've also taken the opportunity to upgrade our Data Acquisition and Dyno Control to Froude's Texcell V12 Data Acquisition and Dyno Control Systems and added two AVL 733S Fuel Balancer Systems. These additions are not just upgrades; they are transformative tools that will dramatically improve the reliability and quality of the data we capture during engine testing. The dynos at the core of this technological leap, the AG150 and AG30, are poised to elevate our development capabilities to the next level. This investment is another example of AIE's unwavering commitment to becoming the world leader in rotary engine innovation and reliability, constantly pushing the state-of-the-art and redefining the possible. #EngineeringInnovation #TechnologyInvestment #EngineTesting #DevelopmentExcellence #Innovation #AerospaceEngineering #UAVTechnology #RotaryEngines #AIE #Froude #dynamometer #enginetestcell #engineering #enginetesting #dynamometers
