    摘要: Optical recording disc having a rigid, dimensionally-stable support which keeps a plastic film taut and flat so that an optically-recordable coating on the plastic film resists the dimensional changes and warping which it otherwise might experience if unsupported. The optically-recordable coating may include an energy-absorbing layer which develops discontinuities immediately upon impingement by a focused laser beam and thus provides DRAW capability.

    摘要: 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.

    摘要: An iron less stator, brushless, single coil motor without laminations uses permanent magnetic field lines co-acting with magnetic field lines from current carrying packets of wires to both start and run the motor.The ironless stator is void of any iron or ferro-magnetic material.It is a brushless design energized with pulses from an electronic circuit.A plurality of wires grouped into packets are paired by two packets, with every pair regarded as an electromagnetic field, having the same number as the motors permanent magnet fields, even though not all packet pairs might be assembled.The stator with packets pairs are placed between two co-axial cylinders, both having attached alternate polarity permanent magnets, with the two cylinders rotating together around the wire packets pairs.The cylinders have a common attachment to a shaft running in bearings in a motor frame.

    摘要: 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. This embodiment also has like number of magnet poles and stator poles for improved motor efficiency, and that also is providing a smooth sine-wave AC power output when used as a generator, and having either an AC or commutated DC circuit energizing said two free coil ends when used as a motor.
