Patent number: 11928980Abstract: A heavy-duty interactive (HDi) system may include a heavy-duty vehicle; a work tool installed on the heavy-duty vehicle; a memory that stores a plurality of patterns representing operation events for the heavy-duty vehicle; a first sensor affixed to the heavy-duty vehicle that collects first sensor data as the heavy-duty vehicle is operated; a second sensor affixed to the work tool that collects second sensor data as the work tool is operated; and a controller operatively coupled to the first sensor, the second sensor, and the memory. The controller may be configured to identify a heavy-duty vehicle operation event by comparing at least one of the first sensor data and the second sensor data with the plurality of patterns in the memory, and associate the work tool with the heavy-duty vehicle based on a comparison of the first sensor data and the second sensor data.Type: GrantFiled: April 26, 2021Date of Patent: March 12, 2024Assignee: Caterpillar Inc.Inventors: Brian B.

Publication number: 20230361635Abstract: A configuration of a plurality of elongate, axially-magnetized curvilinear permanent magnets having high length to cross-section ratio, produced, for example, by the PM-Wire manufacturing process, that produce an electric machine permanent magnet rotor structure with a very low intrinsic demagnetizing field, allowing for operation at high temperature, at high RPM, or enabling use of permanent magnets comprising low coercivity magnetic materials. Exemplary embodiments of two-pole, four-pole, six-pole and eight-pole rotor permanent magnet configurations for single and dual rotor applications. The novel configuration of axially-magnetized curvilinear permanent magnets reduces demagnetization at high temperature, increases electric machine power density, reduces weight by eliminating the need for back iron, increases motor reliability, reduces manufacturing costs, and enables higher electric motor torque and electric generators.Type: ApplicationFiled: July 14, 2023Publication date: November 9, 2023Applicant: Advanced Magnet Lab, Inc.Inventors: Mark Senti, Philippe Masson

Publication number: 20230062147Abstract: A method for continuous manufacture of permanent magnets. A material sheet is formed into an open tube, having a lengthwise opening. Magnetic powder may be poured into the lengthwise opening on a continuous basis. The tube opening is then formed closed and sealed. The magnetic powder is magnetically pre-aligned by subjecting it to a first magnetic field. The tube containing the powder may be compressed into a desired shape, forming an elongated permanent magnet. After compression, the elongated magnet is magnetized by a second magnetic field in two-step process, wherein the elongated permanent magnet is subjected to a magnetic field from first magnetizing coil that is pulsed with a first electric current in a first direction, followed by a second magnetizing coil being pulsed with a second magnetizing electric current in a second direction. The elongated magnet may be formed into any arbitrary shape, such as a ring or coil.Type: ApplicationFiled: November 5, 2022Publication date: March 2, 2023Applicant: Advanced Magnet Lab, Inc.Inventors: Philippe Masson, Mark Senti

Patent number: 10002696Abstract: A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method provides a first insulative layer tubular in shape and including a surface along which a conductor segment may be positioned. A channel formed in the surface of the insulative layer defines a first conductor path and includes a surface of first contour in cross section along a first plane transverse to the conductor path. A segment of conductor having a surface of second contour in cross section is positioned at least partly in the channel and extends along the conductor path. Along the first plane, contact between the conductor surface of second contour and the channel surface of first contour includes at least two separate regions of contact.Type: GrantFiled: November 26, 2014Date of Patent: June 19, 2018Inventors: Gerald Stelzer, Rainer Meinke, Mark Senti
