Electro Permanent Alnico Magnet Gripper

[MagnaProp]

Thanks for the info Kator01 and kEhYo77. Robert Murray-Smith does some really cool stuff. Thanks for the video link.

So if he is switching the poles on an Alnico magnet with an electromagnet, can't just that be used to draw in another magnet then switch the alnco polarity at the right time to push the magnet away for rotating a motor?

If the permanent magnet is constantly pulling or pushing then maybe Lenz force in the coil is less of a problem since the permanent magnet keeps doing work for free in between polarity switching states?

Isn't this just the same as Edward Leedskalins permanent magnet holder?

It appears to be a more powerful system than  with Alnico alone!

Your right, the power looks good.

Not quite the same as a Leedskalins PMH. PMH needs constant electricity if no metal completes the circuit by touching the two open ends of the U shaped metal together. It also only holds indefinitely if metal is touching the open ends to complete the flux circuit.

If the Alnico stators are spaced fare apart enough from each other, then you get some pull and push for free while the rotor part is between stators. The question is can this free "inbetween time" be long enough and strong enough to yield more energy than it takes to do the Alnico pole switch. Or at least be more efficient than current generators are?

So is the Gripper more efficient in using less power? Maybe the strong neo's in the Murray-Smith device are causing a stronger reluctance in the Alnico to switch so it needs more power?

Gripper is 5v at 800mA

Robert Murray-Smith improved Flynn appears to be 12v at 10 amp.
