Respected sir,
As I am looking forward to have an project on electromagnetic suspensions for 2wheelers. I just wanted full report an ppt based on this. Ppt should contain the abstract information about electromagnets design advantages disadvantages and references.

A regenerative damper is a type of damper that converts linear intermittent parasite motion and vibration into useful energy, such as electricity. Conventional shock absorbers simply dissipate this energy as heat.
When used in an electric vehicle or hybrid electric vehicle the electricity generated by the shock absorber can be diverted to its power train to increase the life of the battery. In non-electric vehicles, electricity can be used to power accessories such as air conditioning. Several different systems have recently been developed, although they are still in development stages and not installed in production vehicles.

In 2005 a patent was filed for this type of device. This type of system uses a linear motor / generator composed of a stack of permanent magnets and coils to generate electricity. This system was further developed at Tufts University and has been licensed to Electric Truck, LLC. Preliminary data suggest that 20% to 70% of the energy normally lost in the suspension can be recaptured with this system.

A system developed at Swinburne University of Technology used DC electromagnetic machines as damping elements to generate power for storage in conventional batteries. This system used a device based on principles similar to a "boost" DC-DC converter. The design offered the possibility of optimizing the energy conversion efficiency of the system and also allowing the ability to control the damping coefficient of the damper in such a way that the system could act as a semi-active damper.
