Abstract:
An electrical system including a linear motor in which energized forcer and thruster coils are used for the field and armature elements, respectively. In accordance with various exemplary embodiments, one or more thruster coils may be provided on a reciprocating shaft with opposing single or multiple fixed forcer coils. Using coils as the electromagnets for both forcer and thruster coils advantageously provides necessary power while also minimizing system weight and decreases in magnetism typically encountered with permanent magnets with rising temperature, resulting in higher and more controllable magnetic forces over varying temperatures. A ferrous system housing and open ferrous containers for the thruster coils may be further included to advantageously focus the magnetic forces. Additionally, multiple forcer and thruster coils may be disposed in various arrangements along the reciprocating shaft. Exemplary applications include use of such a system for controlling oscillations of a poppet valve in an internal combustion engine.

Claim (Index 37):
The method of  claim 36 , further comprising:\n applying, to a third forcer coil that is within said ferrous housing and disposed coaxially with and stationary relative to said reciprocating shaft, a fifth voltage having one of fifth mutually opposing polarities and inducing a third forcer magnetic field; guiding at least a portion of said third forcer magnetic field with said ferrous housing; applying, to a third thruster coil that is disposed coaxially with and affixed to said reciprocating shaft, a sixth voltage having one of sixth mutually opposing polarities and inducing a third thruster magnetic field; wherein,\n responsive to applying said fifth and sixth voltages having a combination of said fifth and sixth mutually opposing polarities, said third forcer and thruster magnetic fields are mutually attractive and urge said reciprocating shaft to move said third thruster coil toward said third forcer coil, and \n responsive to applying said fifth and sixth voltages having a different combination of said fifth and sixth mutually opposing polarities, said third forcer and thruster magnetic fields are mutually repellant and urge said reciprocating shaft to move said third thruster coil away from said third forcer coil.
