Adaptive demagnetization compensation for a motor in an electric or partially electric motor vehicle - US Patent 6591925 The permanent magnet induced voltages from traction motor 38 and generator motor 30 are used by controller 100 to determine a state of the permanent magnets contained within traction motor 38 and generator motor 30. In particular, a voltage sensor incorporated in generator motor 30 and a voltage sensor in traction motor 38 determine a voltage that is proportional to the magnetization of permanent magnets in generator motor 30 and traction motor 38, as described below. Based on the state of the permanent magnets in traction motor 38 and generator motor 30, controller 100 determines a current provided by inverters 106, 108; determines whether the traction motor 38 or generator motor 30 are operable; and initiates warnings to a user. www.patentstorm.us /patents/6591925.html   (4646 words)

Roschin & Godin: Magneto-Gravity Effects; Verification of the Searl Effect Homopolar generator may be employed in reverse as a motor to convert electrical energy into mechanical energy. Afterwards the electric motor is completely disconnected by the electromagnetic muff and the ordinary electrodynamics generator is connected to the basic shaft of the device through the same muff. Besides the presence of the iron-concrete ceiling, in immediate proximity from the magnetic system there was a generator and electric motor, which contained some tens KGs of iron and could potentially deform the field's pattern. www.rexresearch.com /roschin/roschin.htm   (8958 words)

dpalma5.txt The upper curve (a) shows the motor armature input power with a constant motor field current of 6 amperes as the speed is varied with no generator magnet excitation and is seen to reach a maximum of 4782 watts as the speed is increased to 6500 rpm. Curve 14b shows the increase of motor armature power over that of curve (a) that results from energizing the generator magnet with a current of 16 amperes but with the generator output switch open so that there is no output current (and hence no output power dissippation). Curve 14c shows the further increase of motor armature input power over that of curves (a) plus (b) that results when the output switch is closed, the generator magnet is energized and output current is produced. www.textfiles.com /conspiracy/dpalma5.txt   (4569 words)

A Boyce's Electrical Webpage on DC Motors Motor construction is physically similar to a generator, in fact, a basic dc generator can also function as a dc motor. A dc motor, like a dc generator, consists of end bells, frame, brush assembly, commutator assembly, armature assembly, and pole pieces. However, a motor also requires dc excitation to the armature. ourworld.compuserve.com /homepages/boyce_smith/dcmotors.htm   (2289 words)

Thoughts The DC Vortex Motor, The Ed gray Engine, The Joe Newman Motor, T. Henry Morray, and Teslas Free Energy devices are all related, They use Radiant Energy and Vortex Energy which you do not know much about. Infact if you will do the experiment that is on the first pages of the 785p Vortex Generator plans you will find that you get about 25 times more energy output, this is why we stated this on the web. His site says 25 times more energy can be extracted from the generator coil- and I certainly don't see it, not even a COP of 1. www.theverylastpageoftheinternet.com /menu/scams/fuelessthoughts.htm   (3440 words)

The Adams Motor Page The Adams Motor Generator is so efficient, so simple and consequently it's construction is such that is surpasses overwhelmingly anything before it, thus lending itself admirably to mass production. The invention may be broadly said to be, an electric motor and/or generator comprising a rotor consisting of a number of radially arrayed permanently magnetized poles, and a stator consisting of a number of radially arrayed permanently magnetized poles, together with a number of wound poles. I found that my original 1970 open magnetic circuit motor generator is superior to my 1976 closed magnetic circuit model in regard to the results of obtaining and maintaining a correct harmonic vacuum oscillation and so tapping gravitational energy during one half-cycle of the gravitational pulse wave. www.geocities.com /CapeCanaveral/Lab/1287/adams/adamsall.htm   (3440 words)

On the Nature of Electrical Induction Contemporary experiments have also shown the Faraday disc to be a superior motor or generator when the fixed exciting magnet is attached to and rotates with it, thereby removing a constant drag which is superimposed on the mechanical input, or output of the machine. It has been known for 100 years that the exciting magnet of a homopolar or Faraday disc motor or generator exhibits no reaction torque to the mechanical forces generated by the polarized disc. The reduced drag obtained by physical connection of the magnet to rotate with the disc in the motor mode is not unambiguously useful since the torque output of the machine is only with respect to the rotating reference frame of the machine. depalma.pair.com /Absurdity/Absurdity09/NatureOfElectricalInduction.html   (3515 words)

The 'N' Effect - Bad Astronomy and Universe Today Forum The homopolar generator would have an application in say the electroplating industry where they need low voltages and high currents and if they had to generate their own power then this sort of machine could be usefull. Most electric motors have 20 to 200 turns of wire each generating or moving in a magnetic field and in this way are very efficient as the voltage(pressure of electricity) is high and current(flow of electricity) is low and so very small sections of wire can be used. Now Micheal Faraday created the first Homopolar generator in (1831, I think), which it essentially what this is, but it was in 1979 that the Sunburst N-machine was made. www.bautforum.com /showthread.php?t=27143   (1795 words)

Homopolar Generator, HPG, Faraday Disk Thomas Strickler, Motional emf's and the Homopolar Motor, AJP 32, 69, (1964). Once we realize that the external circuit is the "stator" of the device, the homopolar generator is not as weird as it first seems. If the mechanical energy input to a homopolar generator is not in perfect 1:1 proportion to its heat output, then there are mysteries here to be investigated. www.amasci.com /freenrg/n-mach.html   (1624 words)

EM Timeline This device is also a DC motor and is homopolar (but not acyclic.) Shown is a model probably made for Faraday in 1823 (notice the difference in the intersection between the wheel and the magnetic poles in Faraday's model and that in the background sketch from Barlow.) FARADAY is asked to investigate electromagnetism and quickly produces his "Electromagnetic Rotator", which is the world's first Electric Motor (and is powered by DC and is non-commutated), and it is also the world's first electromechanical power converter that is both homopolar in structure and "Acyclic" in operational nature. FERRARIS produces and demonstrates his first two rotating field motors for polyphase alternating current. pixii.com /apparatus.htm   (3035 words)

Biomimetic Underwater Robots The fundamental governing concept of the CCCPG model is that the motor output that underlies behavior is generated by genotypically specified central pattern generators that are modulated by peripheral exteroceptive and proprioceptive feedback during behavior (Delcomyn, 1982). The central pattern generators in turn activate motor neurons that are recruited in order of size to grade the intensity of contractions and the resultant lateral flexions (Grillner and Kashin, 1976). The pattern generator responds to the state transition message and desired period parameter from the oscillator, polls the walking command logic and determines through a truth table which synergies should be active and sets or clears the booleans associated with different bifunctional synergies. www.arch.kth.se /eurb/rebrain/background/satellites/eelrobot.htm   (809 words)
