A modified form of apparatus is disclosed, and the preferred and illustrated embodiment thereof utilizes a pulse width modulator circuit to control the duty cycle pulses applied to coils for rotating an engine. The pulse width modulator (PWM) cooperates with an engine distributor system to generate a procession of pulses which are in turn applied to a power transistor to switch the transistor off and on in timed sequence. This applies power to coils for a magnetic engine. Moreover, two coils are included with each piston and are therefore able to be triggered at different intervals. A modified construction is also disclosed including a pair of coils which are serially positioned but independently connected to cooperate with a sleeve and piston telescoped therein and suitable passages for cooling water are also included.
This application is a continuation of application Ser. No. 215,920, filed Dec. 12, 1980, and now abandoned, which is itself a continuation-in-part of application Ser. No. 071,949, filed Sept. 4, 1979, and now abandoned.
A core unit in a linear pulse motor comprising first and second cores, a plurality of magnetic poles formed on the central portion of the first and second cores, a plurality of leg parts formed on both ends thereof, each having concave grooves, first and second supporting shafts fixed to bottom surfaces of the grooves, and first and second rotating rollers supported by the first and second supporting shafts to unite the first and second core integrally. In a method of manufacturing a core unit in a linear pulse motor, the core unit being composed of integrally united first and second cores each including a plurality of magnetic poles formed on the central portion thereof, and leg parts formed on both ends thereof, each having concave grooves, the method comprises the steps of disposing first and second supporting shafts in parallel to each other for supporting rotating rollers, fitting the first and second supporting shafts in the concave grooves, disposing the first and second cores in parallel to each other spaced away in a prescribed interval, and bonding the first and second supporting shafts to the bottom surfaces of the concave grooves for fixing them.
This invention is an engine with reciprocating piston slidingly mounted within a cylinder and connected to a rotatable shaft. The piston is driven back and forth within the cylinder by a pair of electromagnets to obtain rotary power. A secondary winding around one of the electromagnets produces an alternating current. An anti-arc relay is also provided to prevent burning of the high voltage contacts.
A linear motion electric power generator for generating electric current from work done by an intermittent force. A moving magnet is confined so that it can move with bi-directional linear, or approximately linear, motion through each of at least two coils. The coils are spaced apart from each other and connected electrically so that current produced in a first coil as a result of movement of the moving magnet is substantially in phase with current produced in said second coil. Preferred embodiments are described for providing electric power generation from extremely lower power mechanical forces. Embodiments of the invention are useful for providing power for long life flashlights, for alarm systems and for communication devices located at places where conventional electric power sources are unavailable. Another preferred embodiment is a low profile unit which derives its mechanical from repetitive forces such as the forces on the heel of a shoe during walking or running.
The rotor of an electric motor is a crank shaft driven through connecting rods by piston-like reciprocating members powered by superconducting electromagnets. The electromagnets can be solenoids of conventional material cryogenically cooled to superconduct. In the preferred embodiment, the solenoids reside in a thermally insulated chamber filled with liquid gas coolant. The reciprocating members each have a head which is a linearly moveable core of a solenoid The reciprocating members also each have a base which travels in a cylinder defined by a motor block. The motor block can be a conventional block as in an internal combustion engine. A rotating disk having edge commutators electrodes distributes electrical energy to the solenoids in alternating polarity sequences. Sets of solenoids are electrically in parallel to operate in tandem. Conventional internal combustion, piston-driven engines can be modified to be an electric motor as described above.
An electric starter motor and generator is integrated into the structure of an internal combustion engine by making the ferromagnetic pistons of the engine the relatively moving elements in the starter and generator. A coil is solenoidally wound around each sleeve of the engine. An electronically controlled switch sends battery current into an appropriate coil inducing a powerful magnetic field therearound. The magnetic field and piston interact resulting in a powerful magnetic force which moves the piston and thus cranks the engine. At appropriate times in the operation of the engine, fuel to the same can be shut off and the engine run as a high speed electric motor.
