  • Publication number: 20220278580
    Abstract: A motor winding and energizing system using a “Three pulse, odd-even motor winding” wherein first, all odd numbered coils and then all even numbered coils, are wound on a motor stator, and a rotor having alternate polarity magnetic poles, with the rotor rotatably journaled inside the stator. The rotor is having the same number of poles as the total number of coil poles. When an original power pulse is connected to odd coils, out-of-phase induction pulses also occur into adjacent even-numbered coils. thereby diminishing the original power pulse, and the wattage associated with it, causing the rotor, to rotate by the said three pulses, but at a diminished wattage. The motor can have only one, or two or more semiconductors to drive the coils. The motor can have a “magnetic start “position” Alternators and generators can also be altered to benefit by this new winding system. Motors, which can be fractions of HP, can also designed for hundreds of HP.

  • Publication number: 20200076258
    Abstract: Describes a new method for saving 65% of material in fabricating electro-magnetic coils. Made as a series of linear open jaw winding coil slots, in a sheet, with the individual coils connected together with bendable remnants. Several of these sheets can be combined to achieve the desired height, for the best thickness of the coil structure. The individually wound coils can be used as separate coils, in solenoids or in electro-magnetic relays, or combined as a stator, The “connection together” is accomplished by bendable remnants, which can be formed into a circle, and used as a stator. If used with a magnet rotor, the lack of winding slots minimizes “cogging”.

  • Publication number: 20200001731
    Abstract: This invention is for an inexpensive and cost-effective way to patrol and prevent un-authorized personnel from entering or crossing a special one-way roadway. By having continuous surveillance, with the patrol-vehicles having photo equipment, infra-red equipment, radio equipment for contacting proper authority, and having a siren equipped vehicle, it is unlikely for un-authorized personnel from entering or crossing the one-way roadway. The road way is having a left and right fence, preferably made with transparent panels, allowing for visual and infrared surveillance. This surveillance allows for instant detection of any un-authorized person or equipment, The preferred patrol is with a vehicle that is electric and driverless. Signage stating of an addition of an electrified wire, similar to “animal-prevention-fence” prevents personnel from entering the roadway.

  • Publication number: 20160225506
    Abstract: The present invention describes a unique magnetic attraction effect between two soft iron parts. One soft iron part is a profile, with a slot, having a conductor inside the profile. The second soft iron part, named the armature, can have any shape or form, as long as it covers the slot in the profile A short electrical pulse into the conductor permanently attracts the profile and the armature to each other, even after the pulse is removed. This is a unique magnetic attraction, contrary to what is known today, but can also be incorporated into a magnetic effect motor, having a central soft iron rotating rotor surrounded by a plurality of soft iron, square armatures having on the inside a conductor or conductors energized by pulses in synchronism with the rotors angular position, creating continuous rotation of the rotor as long as pulses are supplied.

  • Publication number: 20140176330
    Abstract: This is an inexpensive detector to prevent mass murders by guns, and illegal use of fire arms. Inexpensive antenna bands affixed to ammunition casings or to the barrel or other part of a fire arm activates a detector/sender which is generating specific radio frequencies, and which is also a beam-forming generator. The beam of a specific radio frequency is reflected back to the detector, mounted on a building, or carried by a law enforcer. When the reflected signal from the antenna bands reaches the detector, an output signal is produced in the detector, which is used to alert safety personnel or electronic alarms, that a gun is nearby. It also has several safety features in case the antenna bands are tampered with, or removed.

  • Publication number: 20100225260
    Abstract: A brushless dynamo-electric machine that can be used either as electric generator or electric motor driven by sine wave pulses or by commutated DC pulses. This invention solves a cogging problem between the stator and the rotor, that is inherent in most of today's brushless dynamo's with permanent magnet poles and laminated stator poles. This cogging, in related art, is caused by salient stator poles having winding slots, or gaps, with said gaps interacting with the rotors magnetic fields, causing magnetic reluctance cogging. This embodiments stator is non-salient and has a plurality of mushroom-shaped poles, presenting a congruent periphery of the stator; that is facing the magnets on the rotor. After conjoining of the poles into a stator, all said wound windings are connected together and are terminated in two free coil ends.
