Description

BACKGROUND

1. Field

The disclosure relates generally to magnetic material and more specifically to magnetic material for electromechanical systems for developing magnetism in a desired profile.

2. Description of the Related Art

A magnet is an object or material that produces a magnetic field that exerts attractive forces on opposite poles and repulsive forces on same poles. Magnets can be used in a wide variety of devices that utilize magnetic forces mediated by magnetic fields that result in attractive and repulsive forces between entities.

Magnetic materials are materials that exhibit magnetic properties and can generate and respond to magnetic fields. For example, ferromagnetic material is a type of magnetic material that exhibits strong magnetic properties. Ferromagnetic materials can have spontaneous magnetization so that they can become permanently magnetized in the absence of an external magnetic field.

The atoms in ferromagnetic materials align in a specific pattern to create magnetic domains. Ferromagnetic materials become magnetized and exhibit strong magnetic properties when the magnetic domains created by atoms in ferromagnetic materials are aligned. In this case, ferromagnetic materials can retain magnetization for extended periods, making the ferromagnetic materials useful for several applications such as magnets, transformers, motors, drivers, and sensors.

Intensive properties for magnetic material are the material properties which do not change with the amount of material, and extensive properties for magnetic material are the material properties which change with the amount of material. The behavior of ferromagnetic material can be influenced by environmental factors like temperature, external magnetic fields, and presence of magnetic materials in a close range.

DETAILED DESCRIPTION

The illustrative embodiments recognize and take into account a number of different considerations as described herein. For example, the illustrative embodiments recognize and take into account that functional gradients have been observed to improve material properties across design motifs. These design motifs provide improved material strength and toughness, which are often compromised through other techniques.

The illustrative embodiments also recognize and take into account that functional gradients of ferromagnetic particles can be used to create distributions that result in customized magnetic fields and magnetic characteristics that generate forces between entities.

The illustrative embodiments also recognize and take into account that additive manufacturing has expanded development of functionally graded structures that can be used for many applications. For example, the additively manufactured structure with functional gradients can be used for motors, magnetic resonance imaging scanners, sensors, solenoids, transformers, inductive heaters, and valves.

As used herein, when used with reference to items, “a number of” means one or more of the items. For example, “a number of different types of communication networks” is one or more different types of communication networks. Similarly, “a set of,” when used with reference to items, means one or more of the items.

Further, the term “at least one of,” when used with a list of items, means different combinations of one or more of the listed items may be used, and only one of each item in the list may be needed. In other words, “at least one of” means any combination of items and number of items may be used from the list, but not all of the items in the list are required. The item may be a particular object, a thing, or a category.

For example, without limitation, “at least one of item A, item B, or item C” may include item A, item A and item B, or item B. This example may also include item A, item B, and item C or item B and item C. Of course, any combination of these items may be present. In some illustrative examples, “at least one of” may be, for example, without limitation, two of item A; one of item B; and ten of item C; four of item B and seven of item C; or other suitable combinations.

With reference now to the figures, and in particular, with reference to FIG. 1, an illustration of resultant magnetic force from a number of forces between the functionally graded distribution of magnetic particles paired with permanent magnet is depicted in accordance with an embodiment of this disclosure. In this illustrative example, the functional graded distribution shows a material or structure that exhibits a gradual and controlled variation in its composition. The functional graded distribution shows magnetic properties for magnetic particles paired with permanent magnets through varying volume fraction of magnetic materials.

Volume fraction is the volume of a material feature or constituent in a region relative to the total volume of that region. Volume fraction is unitless and is often reported as a percentage. Volume fraction may indicate proportions of any material feature including but not limited to composition, constituents, arrangements, distribution, grain size, dimensions, orientations, porosity, pore size, phases, crystallinity, and properties. The volume fraction may correspond to a region of any scale such as macroscale, mesoscale, microscale, and nanoscale and is not necessarily indicative of the whole material as the material may be comprised of regions with different volume fractions.

Local magnetic properties are the effective intrinsic and extrinsic magnetic properties of a local region of a material. The local magnetic properties can be influenced by the corresponding mass fraction and volume fraction of the material feature in that region.

In FIG. 1, magnetic property is facilitated by varying magnetic material volume fractions via particle distribution. Particle distributions are paired with permanent magnets such that forces are created from the interaction between magnetic particles and permanent magnets. For example, pairing 100 includes distribution of magnetic particles 104 and permanent magnets 106. In this illustrative example, distribution of magnetic particles 104 includes magnetic particles with a force acting on each particle and the corresponding opposite force acting on the permanent magnets 106. Pairing 102 shows a sum of the vertical components of forces acting on the distribution of magnetic particles 104 and permanent magnets 106. The forces shown in pairing 100 illustrate the effect of particle distribution which results in a net effect shown in pairing 102. In this illustrative example, pairing 100 and pairing 102 can be examples of electromechanical systems or portions of electromechanical systems, and such distributions can be adjusted to facilitate a force profile which changes with position. In other words, distribution of magnetic particles can be adjusted such that electromechanical systems will operate according to the force profile.

In this example, magnetic particles for distribution of magnetic particles 104 can be selected from a number of magnetic materials such as paramagnetic materials, diamagnetic materials, ferromagnetic materials, or particles for any suitable magnetic materials.

In this illustrative example, distribution of magnetic particles 104 can be determined using force profiles for pairing 100 and pairing 102. For example, a force profile that includes information associated with desired forces that are acting on magnetic particles and permanent magnets 106 in pairing 100 can be used to determine distribution of magnetic particles 104. In other words, distribution of magnetic particles 104 can be tailored based on desired forces acting on magnetic particles and permanent magnets.

In this illustrative example, the force profiles for distribution of magnetic particles 104 can include locations of equilibrium, force direction, force magnitude, and any suitable information related to desired forces acting on particles for distribution of magnetic particles 104.

In this example, the distribution of magnetic particles 104 alters the local magnetic properties which affect magnetic force. In this illustrative example, local magnetic properties such as desired physical characteristics and chemical characteristics contribute to performance of magnetic materials used in pairing 100 and pairing 102. Magnetic force can be tailored by customizing the volume fractions for magnetic materials used in pairing 100 and pairing 102. In this example, the volume fractions include concentrations and size of magnetic particles for magnetic materials used in pairing 100 and pairing 102. In this illustrative example, multiple magnetic materials can be used as magnetic materials in pairing 100 and pairing 102. In this illustrative example, electromagnets and multiple permanent magnets having a variety of shapes, sizes, orientations, compositions, and grades can be used for permanent magnets 106. Local magnetic properties associated with magnetic forces as illustrated in pairing 100 and pairing 102 can be customized spatially to form a magnetic property profile associated with a magnetic force profile. Distribution of volume fractions for magnetic particles can be adjusted such that electromechanical systems will operate according to magnetic forces in a force profile.

Further, the magnetic properties of magnetic materials used in pairing 100 and pairing 102 can also be tailored to form a magnetic property profile. In this illustrative example, a magnetic property profile includes local magnetic properties such as desired physical characteristics and chemical characteristics that contribute to performance of magnetic materials used in pairing 100 and pairing 102. For example, the magnetic property profile can include microstructure, dimension, arrangement, orientation, or any suitable physical and structural characteristics for magnetic materials used in pairing 100 and pairing 102. As depicted, local magnetic properties associated with magnetic forces as illustrated in pairing 100 and pairing 102 can be customized spatially to form a magnetic property profile associated with a magnetic force profile.

As a result, distribution of magnetic particles 104 can be determined using the magnetic force profile and the magnetic property profile as depicted above.

In this illustrative example, distribution of magnetic particles 104 can be used to manufacture magnetic materials using manufacturing techniques such as additive manufacturing. In this illustrative example, a manufacturing process plan can be created for manufacturing magnetic materials using distribution of magnetic particles 104. For example, the manufacturing process plan can include configuration of thermodynamic processes, distribution of binders, curing times, path planning, raster planning, or any suitable configuration associated with manufacturing process for magnetic materials.

It should be understood that the illustrated diagram is only one embodiment of the present disclosure. For example, permanent magnets 106 can be replaced by other supporting devices such as electromagnets, springs, bearings, and any suitable mechanisms. In addition, the illustration of pairing 100 and pairing 102 in FIG. 1 is provided as a simplified view for purposes of explaining features in the different illustrative examples. As depicted, pairing 100 and pairing 102 are shown in two dimensions when in actuality, embodiment in one dimension and three dimensions can also be present for distribution of magnetic particles and supporting devices as depicted above. For example, pairing 100 and pairing 102 can include planar distribution and non-planar distribution for magnetic materials.

Magnets are used in a wide variety of electromechanical devices such as motors, magnetic resonance imaging scanners, sensors, solenoids, transformers, inductive heaters, and valves. Some of these devices utilize force developed by magnets which is known as magnetism mediated by magnetic fields resulting in attractive and repulsive forces between entities.

Electromechanical systems with control elements are commonly used to tailor loads and often need components like motors, power sources, drivers, and sensors to complete works. The method illustrated in FIG. 1 provides an opportunity to improve electromechanical systems by using force profiles and magnetic properties that vary spatially. For example, the method illustrated in FIG. 1 can be applied to a motor to alter the magnetic field for purposes of reducing torque ripple. In this example, torque ripple is a phenomenon where torque produced by a motor is not constant throughout its range of motion. In another example, the products created through the method illustrated in FIG. 1 can be used instead of an electromechanical system. In this case, the products can achieve comparable outcomes by using a functionally graded magnetic structure paired with a permanent magnet to develop magnetism in a desired profile without need of a power supply, controller, or sensors.

The pattern then transitions to a third, highest concentration and remains constant at that level.

Magnetic particles for distribution 400 can result in a net horizontal force acting on a permanent magnet along the corresponding path, as illustrated by plot 404. In other words, the magnetic material generated using distribution 400 can result in magnetic forces along the magnetic material that remain constant at two levels and abruptly transition between these two levels.
