  • Publication number: 20150048695
    Abstract: Multiple arrays of linear motors and generators are combined in a radial configuration to provide high mechanical efficiency to deliver power in a single plane of motion to a common crankshaft. Magnet core assemblies for the motors and generators use powerful rare earth magnets positioned within an outer flux containment shell comprising a highly-magnetically-permeable ferrous-alloy to provide high power density. The motor magnet stack is attached directly to a link rod that connects to the crankshaft. Pulsed power is provided to electromagnetic coils coils by microcomputer control, and coil energy is recovered at the ends of the linear stroke. A controller energizes the coils in certain combinations of coil location and polarity in order to produce bi-directional mechanical motion. Energy that is released when coils are switched off is harvested as voltage pulses returned to standby batteries or capacitors, or the electrochemical cells.

  • Patent number: 8946947
    Abstract: A linear stepper motor is used for the displacement of an armature parallel to a stator having N steps. The stator includes (N+2) stator pole pieces which are enclosed by a magnetic guiding element and are each approximately the same distance from neighboring stator pole pieces. Furthermore, at least one coil is located between two stator pole pieces. The armature is enclosed by the stator in the radial direction and has a permanent magnet magnetized parallel to the stator which is disposed between two armature pole pieces. As a result of the reluctance forces, the armature occupies stable idle positions inside the stator in which the stator pole pieces lie opposite the armature pole pieces. By energizing the coils with a short current pulse, the armature can be displaced inside the stator between the different stable idle positions.

  • Patent number: 7768160
    Abstract: Electromagnetic motor with a slider that moves linearly with respect to the stator in either direction. Embodiments include slider internal or external the stator. Slider includes one magnetic flux producing element in all embodiments. Internal slider embodiments stator includes a minimum of three magnetic flux producing elements and a maximum of four such elements. External slider embodiments stator includes two magnetic flux producing elements. All embodiments provide positive slider return to center at rest position. In internal slider embodiments the slider is centered within the stator resulting from either: a combination of a repelling force from a single magnetic flux producing element in opposition to gravitational pull on the slider due to its weight; or equal and opposite repelling forces on opposite sides of the stator from a magnetic flux producing element on opposite sides of the stator all three elements in longitudinal alignment with each other.

  • Patent number: 7762793
    Abstract: A drive mechanism for delivery of infusion medium a coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. The armature may be configured with a reduced diameter by including a coil cup for supporting the coil including a shelf portion defining at least a portion of a pole surface of the coil cup.

  • Patent number: 7705493
    Abstract: The invention claimed is a novel magnetic mirror air bearing for a Michelson interferometer with lateral motion. A precise kinematic mount is used in combination with magnetic fields wherein current can be applied on a centerline to move a piston and mirror laterally without pitch and yaw so as to effect accurate light beam reflection regardless of distance of lateral movement within a defined space. The assembly is able to operate across extended temperature ranges by utilizing materials which expand and contract at similar rates, and contains a thermalizing cavity which will thermalize the gas to avoid temperature induced artifacts.

  • Patent number: 7535328
    Abstract: In an electromagnet switch, a stationary iron core is composed mainly of a base part and a disk part. The base part is faced to a plunger and the disk part is forcedly inserted and fixed to a boss part formed in the base part. The disk part is composed of a metal plate of ferromagnetic substance (iron plate) and another substance plate (made of resin or rubber and the like, for example,) of a smaller spring constant or a larger damping coefficient than that of the metal plate. The metal plate and another substance plate are laminated. Another substance plate absorbs or reduces the impact force when the plunger is electromagnetically attracted toward and collides with the base part. The propagation of a large impact noise or crashing sound is thereby suppressed, and as a result the impact noise can be reduced.

  • Publication number: 20080122299
    Abstract: An electro-magnetic reciprocating engine and method for converting an internal combustion engine to an electro-magnetic reciprocating engine wherein a ferrite magnet is secured to the top of each piston reciprocally disposed in a cylinder, and an electro-magnet spaced apart from said ferrite magnet on the top of each cylinder. The electro-magnets are energized with a constant voltage to create a magnetic field and the ferrite magnets are selectively intermittently polarized when the piston is about one degree past TDC. The ferrite magnets are polarized by contract strike through a distributor allowing the conventional camshaft to provide timing. The distributor is electrically coupled to a DC power source and a capacitor used to provide a stored but adjustable instant burst of voltage to the contact strike to optimize the magnetic field about the ferrite magnet to interact with the magnetic field about the electro-magnet to effect reciprocal motion of the pistons within the cylinders.
