pat. 3469130 Jines, J.E. Magnetic Motor, does it work?

hi all,

i've been thinking about the cam and feel i didn't do a very good job of explaining what i think is the problem.  let me try a different way.

if we look at the roller (73") on the end of the inner end of rod 64 and place a compass rose on it with south (180 degrees) being the part touching the cam track at its inner most point (closest to center point of power shaft), we can then follow the point on the rose that makes contact with the track throughout the cycle.

to start, looking at fig.2 (rotation clockwise), this contact looks to be from south (180 degrees) to about southwest (225 degrees).  if we continued this rotation, we would see this contact point continues out until it reaches the full travel limit.  by the time it gets there, the contact point is at or near west (270 degrees).

this means that less and less force is applied outward and more and more of the force is applied to the side. if it reaches west, no force will be felt outward.  the machine would stop.

the further out the shield is pushed, the more effort to compress the spring is needed.  granted the magnet attraction should get stronger, but remember, it will never be strong enough to overcome the spring.  something needs to be arranged to prevent the contact point moving beyond southwest (225 degrees).

is everyone with me?  any questions so far?

hi all,

maybe everyone needs more time to think about the shielding.

let's address the source of power, the attraction of the rotor block to the stator magnet.

is a block magnet the best shape to give the most attraction in this configuration?  might a cylinder magnet with the north on half the curved surface and south on the other half be better?  my thinking is it would have to lay on its side exposing one or the other pole only.

does it matter?

An important issue is the friction between the shielding plates and the stator surface.
A very simple analysis with hypothetical numbers can show OU less friction more gain.

wings,

i think something like this

http://www.automotioncomponents.co.uk/purchase.php?p_no=L1024&id=27&method=w

will work nicely for the shields.  should prevent shield contact with stator magnet and surrounding parts.

as you can see from the info, coefficients of friction is .003.

thanks for your comments.

on this slide you have to mount the screen in one of the two sides.
Its thickness is not compatible with the patent drawing, to maximize the pull force, the rotor and the stator must be close.

I'd rather start with a test consisting of a pendulum with a mobile shielding operated by his motion, if the oscillation is amplified it is OU.
Or from a device similar to this patent 3899703_PERMANENT_MAGNET_MOTION_CONVERSION

if we attach the rod/bar (64) that the shield is attached to to the car on the slide, i think the space between the rotor block and stator won't change.  it still has to be thick enough to contain the field.  at least with the slide, the shield won't have to drag on any surfaces.

i think any test you can do would be a grand idea!!

i had a look at that patent.  the diverter plate (shield), if built to the size of the drawings, has a fair amount of travel.  of the 2 methods he mentions (solenoid & cam) to move the diverter, which would be your choice?

since there are magnets in the stator and rotor, mostly in repell mode, i think spacing between rotor and stator can be wider without losing as much as jines machine would.  this might be worth its own thread.

let us know how your test go.
