Fig. 10 serves the illustration of the relationship between magnet sequences F1

and magnet rows 701 to 707 of a rotor 1. Fig. an outer surface M1 of a coaxial

first circular cylinder Z1 oriented to the shaft 5 shows 10. The rotor 1 is coaxial 5

arranged to the shaft. The rotor 1 covers twenty-eight dipole magnets 7, which

are on the outer surface M1 arranged.

The dipole magnets 7 of the rotor 1 are in four magnet sequences F1 with in each

case seven dipole magnets 7 arranged. To the better discrimination the four

magnet sequences F1 with the numbers in deep position of 1 to 4 than F1i to FI4

are durchnummeriert. The dipole magnets 7 of the magnet sequences F1 i to FI4

are so arranged and/or. formed that they sieve longitudinal series 701 to 707 with

in each case four uniform dipole magnets 7 distributed on the scope of the first

circular cylinder Z1 on the outer surface M1 train. The dipole magnets 7 of series

701 to 707 lie in a vertical plane longitudinal to the wave axle 50 of the shaft 5.

The dipole magnets of 7 adjacent rows are against each other alternate so offset

that they form axial to the shaft axis 50 a zigzag pattern uniform over the scope

of the circular cylinder Z1. As example is the uniform zigzag pattern, which the

dipole magnets 7 of the adjacent rows 703 and 704 train, in Fig. 10 with a fat line

inner stator 2 exhibits in each case a circle-disc shaped end cap 13 with in eachcase a ball bearing 11 at its two ends. By means of these ball bearings 11 the

inner stator is 2 coaxial 5 stored on the shaft. The shaft is in a typical

embodiment from non magnetic material, e.g. Plastic, made and exhibits a

diameter of 10 to 40 mm and a length from 100 to 400 mm. The inner stator 2

exhibits an inner stator core 12 and whereupon along the outer surface of the

inner stator of 2 arranged magnets 8. The inner stator 2 is connected solid with a

fastener 4, which in a mechanical housing to the receptacle of the apparatus (not

fixed held.

The rotor 1, existing from two mirror-image constructed rotor drums with in each

case a pipe section and a circular disk, is 5 connected by means of screw

connections 10 stationary with the shaft. Each of the rotor drums exhibits

magnets 7. It concerns dipole magnets 7, whose magnetic dipole axles in to the

shaft 5 vertical arranged planes run. Each of the rotor drums is by a hollow-

cylindrical air gap of that radial inner stator 2 and by an annular air gap of the


32/43

attachment disk, arranged within the rotor drums, 4 separate, which represents a

plane of symmetry regarding the two rotor drums of the rotor 1. In a typical

embodiment the annular air gap and the hollow-cylindrical air gap exhibit in each

case a width from 3 to 50 mm. In the circular disks at the faces of the rotor drums

likewise dipole magnets are 700 arranged.

The mass of the rotor 1 and the shaft 5 connected thereby is rotationally

symmetrically distributed, so that with a rotation around the shaft axis 50 no

imbalance arises.

The outside stator 3 consists of two separate annular halves (= stator rings), in

each case with frame 9, magnets 6 and mounting elements to the attachment of

the magnets 6. Everyone the frame consists of an hollow cylinder, at whose both

faces in each case an annular disc arranged is. In this way each of the stator rings

the shaft axis is 50 without frames, i.e. open. Within the frames 9 the magnets 6

are between the mounting elements. Each of the two stator rings in each case one

of the two rotor drums of the rotor is 1 associated. Each of the stator rings is 1

separate by an annular air gap with a width from 3 to 50 mm of the radial rotor

drums of the rotor arranged within the stator rings. The magnets arranged at the

inside of the stator rings and the magnets 8 arranged at the outside of the rotor 1

thus direct face each other 6, only by the annular air gap from each other

separate. Each of the stator rings can become parallel the shaft axis 50 shifted. It

means that the relative position of the outside stator 3 and thus the coverage of

the rotor can become 1 by the outside stator during the operation of the apparatuschanged and adapted.

With the magnets it concerns 6, 7, 8 dipole magnets. In a prefered embodiment

the dipole magnets are 6, 7, 8 as permanent magnets, e.g. existing from the

Materialen SmCo and/or NdFeB, formed. It is however also possible that or the

several dipole magnets are 6, 7, 8 formed as electromagnets. The magnetic flux

density of the magnets 6, 7, 8 preferably lies in a range from 0,4 to 1, 4 tesla.

ribs 121 run regarding the central axis of the circular cylinder 120 radial and are

uniform distributed over the cylinder extent. In this way 121 grooves develop

and/or between the single ribs. Grooves 122. The circular cylinder 120 exhibits a

circular bore along its central axis to the receptacle of the shaft 5. Both in the

base and in the top surface of the cylinder 120 is in each case a disc shaped

recess, is 11 partial arranged in which one of the ball bearings in each case.

The diameter of the stator core 12 amounts to 50 to 500 mm, its height of 100 to

300 mm. The width of the ribs 121 amounts to

residual nine magnets 8 are now toward the shaft axis 50 in uniform

displacement V so arranged that the last magnet locks 8-10 with its right face

flush with the top surface 126 of the inner stator core 12. In this way the

treppenfrmige arrangement of the magnets 8 represented in fig 13 results.

the outside attachment annular disc 41 are solid connected with one another. The

hollow cylinder 40 serves the receptacle and attachment of the inner stator 2 by

screw connections 10. The attachment annular disc 41 is solid connected with amechanical housing (not shown) to the receptacle of the apparatus. The

attachment annular disc 41 exhibits screw connections 10 on its outer periphery.

connected by four attachment columns with one another at both faces ever. In the

central plane between the two housing plates 21a, 21 b the attachment disk 4 is to

the receptacle of the inner stator 2. In the centers of the housing plates 21a, 21bone bore each is for the execution of the shaft 5. On the four attachment columns

20 the guide means are 19, at which the halves of the outside stator are 3 fixed,

slidable arranged. Likewise between the two housing plates 21a and 21 b the

threaded shaft 14 (not shown) runs to the symmetrica Displacement of the guide

means 19, and thus the halves of the outside stator 3 mounted on it.

Fig 21 shows a scheme, which the relative disposition of the magnets 6 of the

outside stator 3, which shows magnets 7 of the rotor 1 and the magnets 8 of the

inner stator 2 in a prefered embodiment. The arrangement refers to a

constellation, with which the two halves of the outside stator to each other are as

far 3 as possible shifted. In the case of this constellation a complete coverage of

the three described magnet-planar results. That north pole of the dipole magnets

6, 7, 8 is with the letter N, that south pole with the letter S indicated.

The air gap G1 between the outer periphery of the inner stator 2 and the inner

periphery of the rotor 1, as well as the air gap G2 between the outer periphery of

the rotor 1 and the inner periphery of the outside stator 3 can become in any

range with a width from 3 to 50 mm selected.

Fig 22 points a schematic arrangement of the three magnet-planar 6, 7, 8 to the

shaft axis 50 vertical in a cutting plane B-B, as in Fig. 11 indicated. In a prefered

embodiment 2 uniform are over the outer periphery of the inner stator of 2

distributed ten magnets 8 on the inner stator. The magnets 6 point in the cutting

plane B-B, i.e. vertical to the shaft axis 50, a trapezoidal cross section up. Each of

the two rotor halves exhibits ever four series to sixteen magnets each 7, which

exhibit a circular cross section in a cutting plane vertical to the their magnetic

dipole axle. The outside stator 3 exhibits ever eighteen magnets 6 on each of its

two halves, which are uniform over the scope each of the two stator halves of

distributed. The magnets 6 exhibit a trapezoidal cross section in the cutting planeB-B. In Fig. 22 is a prefered orientation of the dipole magnets 6, 7, 8 shown. That

north pole of the dipole magnets 6, 7, 8 is with the letter N, that south pole with

the letter S indicated.
