  4. 4. AFPM Motor/Generator Flywheel for Electric Power Stabilization

    University dissertation from Uppsala : Institutionen för teknikvetenskaper

    Author : Juan de Santiago Ochoa; Uppsala universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The study of a motor/generator for flywheel energy storage, meant to smooth the power transients in a vehicular power train, is expounded in this licentiate thesis. The proposed motor/generator has two sets of windings in the stator, rated at different power and voltage levels, and a significant moment of inertia to store energy in the form of rotational kinetic energy.
