Anyone got a 3ph motor to do a quick One-wire bulb circuit by Brian Prater?

[Goat]

Hi All

Well I got the motor running on single phase with the AC input on L1 & L2 and the 60 Watt incandescent bulb from L3 to L2.

The bulb runs fine on L3 to L2 but the bulb shuts off when L2 is disconnected, so no 1 wire bulb or magnetic reconnection on this replication.

Oh well the motor was dirt cheap so no great loss.

Edit:

Brian Prater - One wire bulb - Test1 08/01/2009

Material:

3 phase 1 HP Hemco motor model RB0014FBA
1 - 60 Watt incandescent light bulb
12VDC to 120VAC 400 Watt inverter
12VDC Marine Deep Cycle/Starting Battery - 550 CCA, 140 Reserve Capacity (No Amp Hour rating).

Power Input:

12VDC to 120VAC from 400 Watt inverter.
House A/C socket.


Tests and observations:

Started motor using rope,Plugged to DC/AC inverter, meter showed 90 Watts draw and 120 W with the bulb not very bright but hot to touch after a short period of time. Battery ran for 5 minutes from 12.8 to 12.2 Volts while running the bulb and motor.   

Started motor using rope, plugged to house A/C socket, ran only long enough to test the one wire light after motor was up to speed, no measurements taken.  The bulb Was brighter than from the battery and also hot to touch after a short period of time.

The motor used more than the 60 Watts mentioned in the article so 3/4 HP or less 3 PH motors could bring different results, the original notes by Brian Prater doesn't mention how many HP the motor is but a smaller motor should use less than the 90 Watts that was used on this test using the 1 HP motor.

Cross current vector transformation as H and I have been stating all along

If i am correct the diode plug is here as a cross current vector
transformations  same as how i got the one wire light bulb to work on the RV.

The cross product occurs in the formula for the vector operator curl. It is also
used to describe the Lorentz force experienced by a moving electrical charge in
a magnetic field. The definitions of torque and angular momentum also involve
the cross product.
http://en.wikipedia.org/wiki/Cross_product

where as Pseudovector becomes is a quantity that transforms like a vector under
a proper rotation, but gains an additional sign flip under an improper rotation
(a transformation that can be expressed as an inversion followed by a
proper rotation). The conceptual opposite of a pseudo vector is a (true)
vector or a polar vector.

This concept can be further generalized to pseudoscalars and pseudotensors, both
of which gain an extra sign flip under improper rotations compared to a true
scalar or tensor.

Physical examples of pseudovectors include the magnetic field, torque,
vorticity, and the angular momentum.

The transformations may be continuous (such as rotation of a circle) or discrete
(e.g., reflection
of a bilaterally symmetric figure, or rotation of a regular polygon).
Continuous and discrete transformations give rise to corresponding
types of symmetries. Continuous symmetries can be described by Lie groups while
discrete symmetries are described by finite groups (see Symmetry group).
Symmetries are frequently amenable to mathematical formulation and can be
exploited to simplify many problems

Distinction between vectors and pseudovectors is overlooked, but it becomes
important in understanding and exploiting the effect of symmetry on the solution
to physical systems. For example, consider the case of an electrical current
loop in the z=0 plane: this system is symmetric
(invariant) under mirror reflections through the plane (an improper
rotation), so the magnetic field should be unchanged by the reflection.
But reflecting the actual magnetic field through that plane changes its
signâ€"this contradiction is resolved by realizing that the mirror
reflection of the field induces an extra sign flip because of its
pseudovector nature

http://en.wikipedia.org/wiki/Pseudovector   becomes a real vector

That gets transformed to become non-reflective,
For example, an electrical wire is said to exhibit cylindrical symmetry, because
the electric field strength at a given distance r
from an electrically charged wire of infinite length will have the same
magnitude at each point on the surface of a cylinder (whose axis is the
wire) with radius r. Rotating the
wire about its own axis does not change its position, hence it will
preserve the field. The field strength at a rotated position is the
same, but its direction is rotated accordingly. These two properties
are interconnected through the more general property that rotating any system of
charges causes a corresponding rotation of the electric field.

The two examples of rotational symmetry  - spherical and cylindrical - are each
instances of continuous symmetry.
These are characterised by invariance following a continuous change in
the geometry of the system. For example, the wire may be rotated
through any angle about its axis and the field strength will be the
same on a given cylinder. Mathematically, continuous symmetries are
described by continuous or smooth functions. An important subclass of continuous
symmetries in physics are spacetime symmetries.


Time reversal:
Many laws of physics describe real phenomena when the direction of time
is reversed. Mathematically, this is represented by the transformation.

This may be illustrated by describing the motion of a particle thrown
up vertically (neglecting air resistance). For such a particle,
position is symmetric with respect to the instant that the object is at
its maximum height. Velocity at reversed time is reversed.

maximum height is where the neon peak circuit works best

C, P, and T symmetries
The Standard model
of particle physics has three related natural near-symmetries. These
state that the universe is indistinguishable from one where:
C-symmetry (charge symmetry) - every particle is replaced with its
antiparticle.P-symmetry (parity symmetry) - the universe is reflected as in a
mirror.T-symmetry
(time symmetry) - the direction of time is reversed. (This is
counterintuitive - surely the future and the past are not symmetrical -
but explained by the fact that the Standard model describes local
properties, not global properties like entropy.
To properly time-reverse the universe, you would have to put the big
bang and the resulting low-entropy conditions in the "future". Since
our experience of time is related to entropy, the inhabitants of the resulting
universe would then see that as the past.)
Each of these symmetries is broken, but the Standard Model predicts
that the combination of the three (that is, the three transformations
at the same time) must be a symmetry, known as CPT symmetry. CP violation,
the violation of the combination of C and P symmetry, is a currently
fruitful area of particle physics research, as well as being necessary
for the presence of significant amounts of matter in the universe and
thus the existence of life. !!!!!


More advanced groups

http://en.wikipedia.org/wiki/Lie_group


Lie groups may be thought of as smoothly varying families of
symmetries. Examples of symmetries include rotation about an axis. What
must be understood is the nature of 'small' transformations, e.g.
rotations through tiny angles, that link nearby transformations. The
mathematical object capturing this structure is called a Lie algebra (Lie
himself called them "infinitesimal groups"). It can be defined because
Lie groups are manifolds, so have tangent spaces at each point



http://en.wikipedia.org/wiki/Bose-Einstein_statistics

Fermi-Dirac and Bose-Einstein statistics apply when quantum effects have to be
taken into account and the particles are considered "indistinguishable". The
quantum effects appear if the concentration of particles

How does it become a ampla-phi-R
scalar multiplication is commutative with cross multiplication

http://en.wikipedia.org/wiki/Cross_product

More generally, the result of a cross product may be either a vector
or a pseudovector, depending on the type of its operands (vectors or
pseudovectors). Namely, vectors and pseudovectors are interrelated in
the following ways under application of the cross product:

vector × vector = pseudovectorvector × pseudovector = vectorpseudovector ×
pseudovector = pseudovector

Because the cross product may also be a (true) vector, it may not
change direction with a mirror image transformation. This happens,
according to the above relationships, if one of the operands is a
(true) vector and the other one is a pseudovector (e.g., the cross product of
two vectors). For instance, a vector triple product involving three (true)
vectors is a (true) vector.

. Why is it a 3 phase RV ?

A vector triple product typically returns a (true) vector. More exactly,
according to the rules given in cross product and handedness, the triple product
a × (b × c) is a vector if either a or b × c (but not both) are pseudovectors.
Otherwise, it is a pseudovector. For instance, if a, b, and c are all vectors,
then b × c yields a pseudovector, and a × (b × c) returns a vector

So now we hold the vectors and we call them charge and now you see how it
becomes OU
