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 19):
An apparatus including at least one linear motor, comprising:\n a ferrous housing including a longitudinal axis and defining an interior region terminated at opposing first and second housing ends that include first and second housing apertures disposed coaxially with said longitudinal axis; a shaft disposed coaxially with and movably along said longitudinal axis and including opposing first and second shaft ends extending through said first and second housing apertures; a first forcer coil disposed coaxially with said shaft and affixed within said interior region proximate to said first housing end; a second forcer coil disposed coaxially with said shaft and affixed within said interior region proximate to said second housing end; a first thruster coil disposed coaxially with and affixed to said shaft between said first and second shaft ends; a second thruster coil disposed coaxially with and affixed to said shaft proximate to said first thruster coil; a first open ferrous container that is disposed coaxially with said shaft and circumferentially about said first thruster coil, and is open toward said first forcer coil; a second open ferrous container that is disposed coaxially with said shaft and circumferentially about said second thruster coil, and is open toward said second forcer coil; at least one electrical power source; and a power controller electrically coupled between said at least one electrical power source and said first and second forcer coils and said first and second thruster coils, and including memory and one or more processors configured to store and execute a plurality of instructions that when executed cause electrical power to be applied to said first and second forcer coils and said first and second thruster coils such that said shaft\n is urged to move toward said first housing end to a first longitudinal location, and \n is caused to remain stationary at said first longitudinal location during a time interval.
