DEVELOPMENT OF AUTO-REINFORCE MAGNETIC FLYWHEEL AS REGENERATIVE ENERGY STORAGE FOR AUTOMOBILE ENGINE

The conservation of kinetic energy in automobile engine is very essential. To
keep the kinetic energy in efficient way, an automobile system utilizes an additional
unit that functions as temporary kinetic energy storage called flywheel. However, the
existing flywheels still unable to anticipate energy draining when it receives high rate
of deceleration. This drawback should be eliminated to gain more energy conservation
in the automobile powertrain. To address this issue, the present research proposes a
better flywheel concept with improved energy handling capability. The proposed
flywheel is constructed with multi-inertia discs, called primary flywheel and secondary
flywheel. Furthermore, between the primary and secondary inertias, there are magnets
and conductive plate that would produce a magnetic engagement based on Eddy
current coupling. In this design, the flywheel offers a new advantage that introduces as
an auto-reinforcement feature which means that it has an ability to recover the draining
kinetic energy when drastic deceleration occurs due to sudden loading or sudden
braking.
