Study of a reluctance magnetic gearbox for energy storage system application
By Bruno Fensterseifer DiasLength2h 13m
About this audiobook
Study of a magnetic gearbox for energy storage system application. Contains simulation results and tests carried out to verify the behavior of the torque output as a function of geometric and operation parameters. Focused on magnetic gearboxes with gains of 10 times or higher operating at high speed.
