Abstract: An electrical machine, which may be a motor and/or a generator has a rotor mounted to rotate about an axis. A plurality of magnetic poles are spaced circumferentially around the rotor in the bore. The rotor comprises a shell shaped to provide a toroidal bore centered on the axis. A slit extends circumferentially around the rotor. The slit penetrates through the shell into the bore. The electrical machine also includes a stator that is supported in the bore by one or more supports extending through the slit of the rotor. The stator carries plural windings that are spaced apart around the bore.

Abstract: A forming tool with forced thermal fluid-based spatio-temporal temperature control of a surface of the tool has a subsurface manifold underlying at least a part of a forming surface of the tool and a number P of at least 6 ports, each port fluid coupled respectively to the manifold via respective channels, where the ports exit the tool at disparate points, with each pair of ports in fluid communication via the manifold. This structure allows manifold path diversity for varying thermal fluid supply and drainage. The manifold may be reinforced.

Abstract: The present disclosure is directed towards a method of manufacturing a permanent magnet such that the magnet defines a channel for allowing circulation of a coolant through the permanent magnet, or defines a channel for allowing circulation of the coolant through an interface between the permanent magnet and a substrate. Magnets made by this method may be useful for manufacturing and/or operating a machine, such as a motor, engine, or sensor.

Abstract: According to an aspect, a rotor for a Synchronous Reluctance Motor (SynRM) is provided. The rotor core includes alternating layers of radially fabricated flux carrier and flux barrier material, defining flux barriers extending through the core without bridges and/or center-posts. In some embodiments, the alternating layers include layers of permanent magnet (PM) and soft magnetic composite (SMC) material fabricated on, and adhered directly to, the rotor shaft. A corresponding method for manufacturing the SynRM is also provided.

Abstract: A method of coating a surface of a substrate with a particulate coating material, the method comprising: determining at least an area of the surface of the substrate to be covered with the particulate coating material; subjecting at least a portion of the area of the surface of the substrate to laser irradiation to form a plurality of distinct spaced-apart laser impact craters in a pattern and/or at least one last impact pit on the surface of the substrate; and thermally spraying the area of the surface of the substrate with the particulate coating material. A coated substrate comprising: a substrate having a plurality of distinct spaced-apart laser impact craters in a pattern and/or at least one laser impact pit on at least an area of a surface of the substrate; a thermally-sprayed coating mechanically bonded to at least the area of the surface of the substrate.

Abstract: Method and apparatus for recording and/or indicating a function of two variables, characterized in that a signal having a value Z which is a function of two variables X and Y is quantified and is then represented in quantified form. The representation in quantified form is effected by projecting a luminous spot on a display area at the point of coordinates (X, Y) wherein the luminosity of the spot represents the quantified form of the value Z.
