DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE DISCLOSURE

[0045] In the following description, the various embodiments of the present disclosure will be described with respect to the enclosed drawings. As required, detailed embodiments of the embodiments of the present disclosure are discussed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the embodiments of the disclosure that may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

[0046] The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present disclosure only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present disclosure. In this regard, no attempt is made to show structural details of the present disclosure in more detail than is necessary for the fundamental understanding of the present disclosure, such that the description, taken with the drawings, making apparent to those skilled in the art how the forms of the present disclosure may be embodied in practice.

[0047] As used herein, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. For example, reference to “a magnetic material” would also mean that mixtures of one or more magnetic materials can be present unless specifically excluded.

[0048] Except where otherwise indicated, all numbers expressing quantities used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and claims are approximations that may vary depending upon the desired properties sought to be obtained by embodiments of the present disclosure. At the very least, and not to be considered as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding conventions.

[0049] Additionally, the recitation of numerical ranges within this specification is considered to be a disclosure of all numerical values and ranges within that range (unless otherwise explicitly indicated). For example, if a range is from about 1 to about 50, it is deemed to include, for example, 1, 7, 34, 46.1, 23.7, or any other value or range within the range.

[0050] As used herein, the indefinite article “a” indicates one as well as more than one and does not necessarily limit its referent noun to the singular.

[0051] As used herein, the terms “about” and “approximately” indicate that the amount or value in question may be the specific value designated or some other value in its neighborhood. Generally, the terms “about” and “approximately denoting a certain value is intended to denote a range within ±5% of the value. As one example, the phrase “about 100” denotes a range of 100±5, i.e., the range from 95 to 105. Generally, when the terms “about” and “approximately are used, it can be expected that similar results or effects according to the disclosure can be obtained within a range of ±5% of the indicated value.

[0052] As used herein, the term “and/or” indicates that either all or only one of the elements of said group may be present. For example, “A and/or B” shall mean “only A, or only B, or both A and B”. In the case of “only A”, the term also covers the possibility that B is absent, i.e., “only A, but not B”.

[0053] The term “substantially parallel” refers to deviating less than 20° from parallel alignment and the term “substantially perpendicular” refers to deviating less than 20° from perpendicular alignment. The term “parallel” refers to deviating less than 5° from mathematically exact parallel alignment. Similarly, “perpendicular” refers to deviating less than 5° from mathematically exact perpendicular alignment.

[0054] The term “at least partially” is intended to denote that the following property is fulfilled to a certain extent or completely.

[0055] The terms “substantially” and “essentially” are used to denote that the following feature, property or parameter is either completely (entirely) realized or satisfied or to a major degree that does not adversely affect the intended result.

[0056] The term “comprising” as used herein is intended to be non-exclusive and open-ended. Thus, for instance a coating composition comprising a compound A may include other compounds besides A. However, the term “comprising” also covers the more restrictive meanings of “consisting essentially of” and “consisting of”, so that for instance “a coating composition comprising a compound A” may also (essentially) consist of the compound A.

[0057] The various embodiments disclosed herein can be used separately and in various combinations unless specifically stated to the contrary.

[0058] FIG. 1 shows an exemplary magnet array structure (MAS) that includes a plurality of magnet arrays in accordance with aspects of the disclosure. The plurality of magnet arrays can include a first magnet array 1 and a second magnet array 3. As shown in FIG. 1, first magnet array 1 may include a first repeatable magnet arrangement 2, and the second magnet array 3 comprises a second repeatable magnet arrangement 4. First and second repeatable magnet arrangements 2 and 4 are shown here configured as a modified Halbach array.

[0059] FIG. 2 shows a plurality of magnetic elements, which can be configured in repeatable magnet arrangements in accordance with aspects of the disclosure. Each magnetic element configuration (MEC) in the repeatable magnet arrangements is a customized magnet, characterized by certain dimensions and remnant magnetization strength. An arrow shown in each MEC depicts the direction of magnetic flux (or magnetization direction). For example, a first MEC 11 has an arrow pointing downwards (along the page), indicating a downwardly-directed magnetic flux.

[0060] The plurality of magnetic elements in FIG. 2 includes first MEC 11 and a second MEC 12. First MEC 11 has a first width 90 and a first height 95 and second MEC 12 has a width equal to (or approximately equal to) first width 90 and a height equal to (or approximately equal to) the first height 95. However, while first MEC 11 has a downwardly-directed magnetic flux, second MEC 12 has an upwardly-directed magnetic flux.

[0061] The plurality of magnetic elements further includes a third MEC 13, a fourth MEC 14, a fifth MEC 15, a sixth MEC 16, a seventh MEC 17, an eighth MEC 18, a ninth MEC 19, and a tenth MEC 20, each of which have a width equal to (or approximately equal to) a second width 91 and a height equal to (or approximately equal to) the first height 95. In the illustrated arrangement of the plurality of magnetic elements, third MEC 13 has a left and downwardly-directed magnetic flux; fourth MEC 14 has a leftwardly-directed magnetic flux; fifth MEC 15 has a left and upwardly-directed magnetic flux; sixth MEC 16 has an upwardly-directed magnetic flux; seventh MEC 17 has a right and upwardly-directed magnetic flux; eighth MEC 18 has a rightwardly-directed magnetic flux; ninth MEC 19 has a right and downwardly-directed magnetic flux; and tenth MEC 20 has a downwardly-directed magnetic flux.

[0062] Additionally, the plurality of magnetic elements can include an eleventh MEC 21, a twelfth MEC 22, a thirteenth MEC 23, a fourteenth MEC 24, a fifteenth MEC 25, and a sixteenth MEC 26, each of which have a width equal to (or approximately equal to) a third width 92 and a height equal to (or approximately equal to) the first height 95. In the illustrated arrangement of the plurality of magnetic elements, eleventh MEC 21 has a right and downwardly-directed magnetic flux; twelfth MEC 22 has a downwardly-directed magnetic flux; thirteenth MEC 23 has a left and downwardly-directed magnetic flux; fourteenth MEC 24 has a left and upwardly-directed magnetic flux; fifteenth MEC 25 has an upwardly-directed magnetic flux; and sixteenth MEC 26 has a right and upwardly-directed magnetic flux.

[0063] As is apparent from FIG. 2, while each MEC in this exemplary embodiment has a same or approximately same height 95, first width 90 (of MECs 11, 12) is approximately three times as long as second width 91 (of MECs 13-20), which is approximately three times as long as third width 92 (MECs 21-26). It should be understood that the varying widths are exemplary, in that the first, second, and third widths 90, 91, 92 demonstrate that the plurality of magnetic elements can comprise MECs with varying widths and magnetic fluxes in order to achieve desired magnetic field strengths. Further, the individual MECs can be arranged adjacent each other via adhesive bonding or gluing and/or coupled together via arrangement in a housing or mechanically coupled via connectors.

[0064] In embodiments, not all MECs depicted in FIG. 2 are used to create the MAS. Additionally, alternative magnetic arrays can be created by modifying embodiments of this disclosure to include additional MECs.

[0065] FIG. 3 shows first repeatable magnet arrangement 2 and second repeatable magnet arrangement 4 in accordance with aspects of the disclosure. In this exemplary embodiment, first repeatable magnet arrangement 2 includes a first plurality of magnetic elements, such as a first MEC 31, a second MEC 32, a third MEC 33, a fourth MEC 34, a fifth MEC 35, a sixth MEC 36, a seventh MEC 37, an eighth MEC 38, a ninth MEC 39, a tenth MEC 40, an eleventh MEC 41, a twelfth MEC 42, a thirteenth MEC 43, a fourteenth MEC 44, a fifteenth MEC 45, and a sixteenth MEC 46. By way of non-limiting example, it is noted that, starting from MEC 31, the magnetic flux of which is pointing downward, the magnetic flux of each successive MEC (moving to the right) is offset 45° from its adjacent MECs, such that the magnetic flux “rotates” counter-clockwise, consistent with an “M8 Halbach” magnetic array.

[0066] Second repeatable magnet arrangement 2 in this exemplary embodiment includes a second plurality of magnetic elements, such as a seventeenth MEC 47, an eighteenth MEC 48, a nineteenth MEC 49, a twentieth MEC 50, a twenty-first MEC 51, a twenty-second MEC 52, a twenty-third MEC 53, a twenty-fourth MEC 54, a twenty-fifth MEC 55, a twenty-sixth MEC 56, a twenty-seventh MEC 57, a twenty-eighth MEC 58, a twenty-ninth MEC 59, a thirtieth MEC 60, a thirty-first MEC 61, and a thirty-second MEC 62. By way of non-limiting example, it is noted that, starting from MEC 47, the magnetic flux of which is pointing downward, the magnetic flux of each successive MEC (moving to the right) is offset 45° from its adjacent MECs, such that the magnetic flux “rotates” clockwise, consistent with an “M8 Halbach” magnetic array.

[0067] In the exemplary embodiment of FIG. 3, first and seventeenth MECs 31, 47 generally correspond to the first MEC 11 depicted in FIG. 2; second and thirty-second MECs 32, 62 generally correspond to third MEC 13 in FIG. 2; third, eleventh, twenty-third, and thirty-first MECs 33, 41, 53, 61 generally correspond to fourth MEC14 in FIG. 2; fourth, twelfth, twenty-second, and thirtieth MECs 34, 42, 52, 60 generally correspond to fifth MEC 15 in FIG. 2; fifth, thirteenth, twenty-first, and twenty-ninth MECs 35, 43, 51, 59 generally correspond to sixth MEC 16 in FIG. 2; sixth, fourteenth, twentieth, and twenty-eighth MECs 36, 44, 50, 58 generally correspond to seventh MEC 17 in FIG. 2; seventh, fifteenth, nineteenth, and twenty-seventh MECs 37, 45, 49, 57 generally correspond to eighth MEC 18 in FIG. 2; eighth and twenty-sixth MECs 38, 56 generally correspond to eleventh MEC 21 in FIG. 2; ninth and twenty-fifth MECs 39, 55 generally correspond to twelfth MEC 22 in FIG. 2; tenth and twenty-fourth MECs 40, 54 generally correspond to thirteenth MEC 23 in FIG. 2; and sixteenth and eighteenth MEC 46, 48 generally correspond to ninth MEC 19 in FIG. 2.

[0068] FIG. 3 further shows that first repeatable magnet arrangement 2 and the second repeatable magnet arrangement 4 have similar magnetic element configurations. However, to mitigate attractive forces between first magnet array 1 and second magnet array 3, second repeatable magnet arrangement 4 can be longitudinally offset from first repeatable magnet arrangement 2. In the exemplary embodiment, MEC 47 of second repeatable magnet arrangement 4 can be arranged opposite MECs 37-41 of first repeatable magnet arrangement 3.

[0069] FIG. 4 shows first and second magnet arrays 1, 3 of the MAS. Moreover, a magnetic field 7 generated between the magnetic elements of the longitudinally offset first and second repeatable magnet arrangements 2, 4 of first and second magnet arrays 1, 3 is depicted.

[0070] FIG. 5 shows a free-body diagram of the magnetic elements of first repeatable magnetic arrangement 2 in accordance with aspects of the disclosure. Second repeatable magnetic arrangement 4, the constituent magnetic elements of which are not shown in FIG. 5, is shown in its location offset, as in FIG. 3, from first repeatable magnetic arrangement 2. A direction of resulting magnetic forces acting on the magnetic elements of first repeatable magnet arrangement 2 is depicted in each magnetic element. This resulting magnetic force acting on the magnetic elements results from the offset arrangement of the first and second repeatable magnet arrangements 2, 3. A reference line 101 runs through and parallel to first repeatable magnet arrangement 2.

[0071] A magnetic force acts on each magnetic element of first repeatable magnet arrangement 2. This magnetic force results from the proximately arranged magnetic elements within first repeatable magnet arrangement 2 and from the proximately arranged magnetic elements within oppositely arranged and offset second repeatable magnet arrangement 4. Thus, it is understood that each magnetic force comprises a first force component in a direction parallel to reference line 101 and a second force component in a direction perpendicular to reference line 101.

[0072] A first magnetic force 211 is applied to first MEC 31; a second magnetic force 212 is applied to second MEC 32; a third magnetic force 213 is applied to third MEC 33; a fourth magnetic force 214 is applied to fourth MEC 34; a fifth magnetic force 215 is applied to fifth MEC 35; a sixth magnetic force 216 is applied to sixth MEC 36; a seventh magnetic force 217 is applied to seventh MEC 37; an eighth magnetic force 218 is applied to eighth MEC 38; a ninth magnetic force 219 is applied to ninth MEC 39; a tenth magnetic force 220 is applied to tenth MEC 40; an eleventh magnetic force 221 is applied to eleventh MEC 41; a twelfth magnetic force 222 is applied to twelfth MEC 42; a thirteenth magnetic force 223 is applied to thirteenth MEC 43; a fourteenth magnetic force 224 is applied to fourteenth MEC 44; a fifteenth magnetic force 225 is applied to fifteenth MEC 45; a sixteenth magnetic force 226 is applied to sixteenth MEC 46.

[0073] For the force components parallel to reference line 101, second magnetic force 212 cancels sixteenth magnetic force 226, third magnetic force 213 cancels fifteenth magnetic force 225, fourth magnetic force 214 cancels fourteenth magnetic force 224, fifth magnetic force 215 cancels thirteenth magnetic force 223, sixth magnetic force 216 cancels twelfth magnetic force 222, seventh magnetic force 217 cancels eleventh magnetic force 221, and eighth magnetic force 218 cancels tenth magnetic force 220. Further, in the direction parallel to reference line 101, first and ninth magnetic forces 211, 219 are negligible. The result is no net magnetic forces on magnetic arrangement 2 parallel to reference line 101, as they are locally canceled out.

[0074] For the force components perpendicular to reference line 101, the first, second, fourth, sixth, twelfth, fourteenth, and sixteenth magnetic forces 211, 212, 214, 216, 222, 224, 226 are negligible. Further, for the force components perpendicular to reference line 101, third and fifteenth magnetic force 213, 225 oppose the fifth and thirteenth magnetic forces 215, 223, and the seventh, eighth, tenth, and eleventh magnetic forces 217, 218, 220, 221 oppose the ninth magnetic force 219. The result is no net magnetic forces on magnetic arrangement 2 parallel to reference line 101, as they are locally canceled out.

[0075] In embodiments, the magnetic elements in first repeatable magnet arrangement 2 and second repeatable magnet arrangement 4 are formed together and are encased within a fixed magnet housing structure, such as an electric motor or custom designed rigid part. As shown in FIG. 5, a large magnetic force (the ninth magnetic force 219) is focused within ninth magnetic element 39. The seventh, eighth, tenth, and eleventh magnetic forces 217, 218, 220, 221 are arranged to oppose the ninth magnetic force 219, which transfers an overall force applied to first repeatable magnet into multiple opposing shear forces that are applied to the first plurality of magnetic elements. Any residual magnetic force that is not locally cancelled out can be countered by the fixed magnet housing.

[0076] Because first repeatable magnet arrangement 2 can be repeated within first magnet array 1 and second repeatable magnet arrangement 4 can be repeated within second magnet array 2—and because first magnet array 1 and second magnet array 2 have a fixed orientation—the magnetic field 7 described in FIG. 4 and the plurality of magnetic forces demonstrated in FIG. 5 repeat throughout first magnet array 1. Deviations in magnetic field 7 and the plurality of magnetic forces can arise due to irregularities in magnetic elements—such as width and strength—and due to being near the beginning or end of the MAS.

[0077] Further, since first repeatable magnet arrangement 2 and second repeatable magnet arrangement 4 are similar, the magnitude of magnetic forces applied to second repeatable magnet arrangement 4 will be similar to the magnitude of magnetic forces applied to first repeatable magnet arrangement 2. However, because the second plurality of magnetic elements in second repeatable magnet arrangement 4 have different orientations than the magnetic elements in first repeatable magnet arrangement 2, the direction of magnetic forces applied to the second repeatable magnet arrangement 4 may differ.

[0078] Despite the differing orientations of the magnetic forces applied to second repeatable magnet arrangement 4, these magnetic forces will cancel out locally (similarly to the magnetic forces applied to first repeatable magnet arrangement 2).
