• A design example of an 8-pole radial AMB for flywheel energy storage 

      Daoud, Mohamed I.; Abdel-Khalik, A. S.; Massoud, A.; Ahmed, S.; Abbasy, Nabil H. ( IEEE , 2012 , Conference Paper)
      High speed flywheel energy storage systems normally use magnetic bearings to reduce friction loss. Bearing load consists of radial forces with or without axial forces according to drive configuration and requirements. The ...
    • Fault-tolerant control of five-phase current source inverter for medium-voltage drives 

      Elgenedy, M.A.; Abdel-Khalik, A.S.; Elserougi, A.; Ahmed, Shehab; Massoud, A. ( Institution of Engineering and Technology , 2014 , Conference Paper)
      Multiphase Machines offer a promising solution to many practical challenges due to their advantages over the three phase counterparts, as fault-tolerant capability and lower torque ripple magnitude. Among different multiphase ...
    • On the development of flywheel storage systems for power system applications: A survey 

      Daoud, Mohamed I.; Abdel-Khalik, A. S.; Massoud, A.; Ahmed, S.; Abbasy, Nabil H. ( IEEE , 2012 , Conference Paper)
      Energy storage systems cannot be considered energy sources but having the ability of storing and discharging energy. They have a vital rule in the reliability and power quality of power systems. There are several energy ...
