Direct Conversion of Magnetic Field of<br />

Constant Magnets <strong>Energy</strong> and Its Application<br />

In Power Engineering and Mechanics<br />

Global and ever increasing energetic and<br />

ecological crises of the Earth prompt scientists<br />

and engineers to scan for new alternative,<br />

pollution-free sources of energy, among them<br />

based on constant magnets and electrets [1-4].<br />

The well-known magnetic engines (ME) by<br />

Serl, Minato and Floyd are unfortunately not<br />

perfect, but they marked the beginning of ME<br />

history and development [1]. The article lists<br />

original designs of new, totally non-current ME.<br />

In spite of the fact, that magnetic nature has<br />

not been totally solved yet, constant magnets<br />

are really bringing us to revolution in energetic<br />

and mechanics. Huge headway in the sphere of<br />

constant magnets permits us to anticipate in the<br />

not too distant future the creation of magnetic<br />

motor generators and other useful devices based<br />

on their principles, with capacity up to 100- 200<br />

kW.<br />

Non-contact Magnetic Rotational Bearing of<br />

Rotation<br />

Bearings are the most widespread and<br />

important element of many devices, ranging<br />

from a motorcar to a spaceship and rocket.<br />

However, the mechanical bearings have<br />

practically exhausted their potentialities. They<br />

wear out rapidly, need regular maintenance and<br />

are short-lived. Moreover, mechanical bearings<br />

have a limitation on speed of rotation and<br />

reliability that limits the area of their usage.<br />

There are electromagnetic non-contact<br />

rotational bearings. Still they are rather<br />

complicated and expensive devices. Headway<br />

in updating the properties of constant magnets<br />

allows creating a high-capacity, simple in design<br />

and totally non-contact magnetic bearing. Fig.<br />

cylindrical magnets 2, 3 compensates the loads<br />

on shaft 6 on radial axis. Force repulsion of end<br />

magnets 4, 5 from stator and rotor magnets 2, 3<br />

compensates axial loads of the bearing. As a<br />

result we have a self-balancing, totally nocurrent<br />

magnetic dynamic system of noncontact<br />

shaft suspension 6. Such a progressive<br />

and prospective application of constant magnets<br />

allows creating a cheap non-contact bearing,<br />

simple in design, with no outage and with<br />

unlimited economic life.<br />

To simplify the draft, Fig. 1 doesn’t show some<br />

small parts of the magnetic bearing.<br />

The main distinctive feature of this simple and<br />

elegant engineering solution is the unique<br />

combination of magnets along the two<br />

coordinate axes to automatically compensate<br />

axial ad radial load on the shaft of the bearing.<br />

If high-tech is applied to create a precise model<br />

of such a non-contact suspension, observing the<br />

minimal clearances of a split millimeter width<br />
