Impermeable Stacking by Feintool Enables Integrated Cooling for Motors 

April 6, 2023 admin 0

Whether the power source is battery or fuel cell, the efficiency and performance of motors are crucial in electromobility. Critical factors in their design and production include stability of the lamination stacks of electrical steel and their impermeability to cooling fluid. Feintool says that its glulock Multiple Dots bonding process promises tight and stable electric motors, even in the high-temperature range prevalent in today’s e-motors. Based in Switzerland, the company develops machinery and processes for both the production of motor laminations as well as fineblanking of bipolar plates for fuel cells.  […]

800V Electric Vehicles Charge into Mainstream with SiC Power Electronics 

March 14, 2023 admin 0

The demand for electric vehicle power electronics will increase dramatically in the next ten years, primarily driven by rapid growth in the battery EV car market, where market analyst IDTechEx of Cambridge, UK, predicts a 15% CAGR globally over the next decade. Currently, the weighted-average battery capacity of BEV cars is increasing in all regions, piling pressure on battery supply chains, and creating uncertainty. The result is that drive cycle efficiency must come to the forefront of powertrain design, meaning the time has come for high voltage wide bandgap power electronics. […]
