    Abstract : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. READ MORE

  7. 25. Synchronous Machines with High-Frequency Brushless Excitation for Vehicle Applications

    Author : Junfei Tang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrically Excited Synchronous Machines; Machine Modeling; Brushless Excitation; Machine Control; Machine Design; Electric Vehicles;

    Abstract : Electrically excited synchronous machines (EESM) are becoming an alternative to permanent magnet synchronous machines (PMSM) in electric vehicle (EV) applications. This mainly attributes to the zero usage of rare-earth material as well as the capabilities of high starting torque and good field weakening provided by EESM. READ MORE
