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 33):
The method of  claim 29 , further comprising:\n guiding at least a portion of said first forcer magnetic field with a ferrous housing enclosing at least said first forcer coil; applying, to a second forcer coil that is within said ferrous housing and disposed coaxially with and stationary relative to said reciprocating shaft, a third voltage having one of third mutually opposing polarities and inducing a second forcer magnetic field; and guiding at least a portion of said second forcer magnetic field with said ferrous housing; guiding at least a portion of said first thruster magnetic field with a ferrous sleeve disposed circumferentially about said first thruster coil; wherein,\n responsive to applying said third and second voltages having a combination of said third and second mutually opposing polarities, said second forcer and first thruster magnetic fields are mutually attractive and urge said reciprocating shaft to move said first thruster coil toward said second forcer coil, and \n responsive to applying said third and second voltages having a different combination of said third and second mutually opposing polarities, said second forcer and first thruster magnetic fields are mutually repellant and urge said reciprocating shaft to move said first thruster coil away from said second forcer coil.
