Linear electrodynamic system and method

Abstract

An exemplary description provided for patent searches includes a linear electrodynamic system for conversion of mechanical motion into electrical power or conversion of electrical power into mechanical motion involving advantageous use of magnetic material positioned on a mover. Bore surfaces of the magnetic material is shape complementary to bore surfaces of stator poles. Some implementations utilize non-annularly shaped bore surfaces while others utilize annularly shaped bore surfaces.

Problems solved by technology

These electrodynamic systems require substantial mass in their construction for adequate performance.

Unfortunately, the amount of mass involved with these linear electrodynamic systems can be undesirable, for example, with situations where construction or operational costs are dependent upon equipment weight.

As another example, for portable equipment, the amount of mass used for these linear electrodynamic systems can lessen the ease of use of the equipment.
