A brushless DC motor with no back EMF - E-Orbo current/voltage traces.

complete load of rubbish. it only a Glorified version of this http://www.youtube.com/watch?v=oyzFk...eature=related
they have next to no torque and you phisicaly have to get them rotating yourself for the magnetes to start repeling one and anouther
you can clearly see him spin it with his fingers behind it to get it going in the orbe vid
or is it just a joke vid?

I have been following Steorn for quite some time, and what they have shown is actually very interesting and when you look at the technology, it is actually very simple.
It also looks like quite a few people have replicated the technology.
And dont forget that Steorn are showing this to the public, so if you want a trip to ireland, you can see it working.

The main focus is that the coils are a closed loop system and from what i can make out,
It is basically a brushless 4 pole toridial coil motor.
The magnets are attracted to the iron in the toridial coils and when the coils are energized the iron is no longer seen by the magnets so the magnets do not stop in position by the coils.
The current is controlled and switched in the coils in such a way that the rotor continues to spin.
The real difference with this motor is that the current required to turn the rotor does not increase with load.
Because the coils are used to saturate the iron and hide it from the magnets the current does not go up with load and there is no BEMF.
So if it works, and it looks like it does, then the amount of current used to energize the coils will stay consistant regardless of the load because the coils are within a closed loop system.


Looks like they may have something after all.
Time will tell, but it is does proove to be a workable technology, this could change the world....


Lets hope...
