Abstract: An annular stator assembly includes a plurality of stator segments. Each stator segment includes a plurality of laminates having magnetic permeable properties; a plurality of thermally conductive laminates positioned between the permeable laminates; and a cooling pipe extending through the laminates for transferring heat from the laminates to coolant flowing through the cooling pipe. The stator segments are constructed independently. Coils are wound on each segment. The stator segments with the wound coils are subsequently arranged to form the annular stator assembly.

Abstract: Provided are a power management system and method. At least one frame module includes at least one bay and a plurality of first connectors at a rear portion of the at least one bay and at least one power conversion unit positioned in the at least one bay. The at least one power conversion unit includes a plurality of second connectors. Each second connector is removably coupled to a first connector of the plurality of first connectors. The first and second connectors include a combination of high power, cooling, and control connectors.

Abstract: A rotor magnet retention device comprises a retainer body and a fastening device. The retainer body includes a bottom region, at least two angled side regions extending from the bottom region, and at least one opening extending through a bottom surface of the retainer body. The fastening device extends through the opening at a bottom surface of the retainer body to a rotor to flexibly position the retainer body relative to the rotor. A first angled side surface conformably communicates with a first magnet coupled to the rotor and a second angled side surface conformably communicates with a second magnet coupled to the rotor.

Abstract: Permanent magnets are mounted on a rotor of an electrical motor by an apparatus that keeps an adhesive bonding layer between the magnet and rotor in compression over wide variations in temperature and speed of rotation. The mechanical stresses on the magnets are controlled using compliant layers and spacers. The apparatus allows the removal and replacement of individual magnets.

Abstract: An apparatus and method for controlling an actuator system having an electrical actuator in hydraulic communication with a hydraulic actuator are described. The apparatus includes a controller module in communication with a source of electrical power and a transceiver. The transceiver is adapted for bi-directional wireless communication with a remote transceiver for the transfer of control data and feedback data. The controller module sends a control signal to the electrical actuator in response to control data received from the remote transceiver. The source of electrical power includes a hydraulic motor and an electrical generator to provide local electrical power from a hydraulic flow. Because the electrical power is generated locally and the control and feedback data are carried over the wireless link, no wires to remote locations are required.

Abstract: An arrangement of coils of different configurations for use in the stator of a slotless radial gap electromotive machine is described. The coils include coils of a first configuration and a second configuration. Each coil includes longitudinal sections and circumferential sections that form a substantially rectangular opening in the coil. The coils are nested together along the inside of a stator core so that the longitudinal sections of each coil of the first configuration are disposed in the rectangular openings of neighboring coils of the second configuration, and the longitudinal sections of the coils of the second configuration are disposed in the rectangular openings of neighboring coils of the first configuration. Other configurations of coils can be nested together inside the stator core to provide one or more additional layers of stator coils.

Abstract: An apparatus for determining the angular position of a rotating component having a plurality of angularly spaced magnetic elements is described. The apparatus includes a sensor board and a processor circuit. The sensor board is disposed adjacent to the rotating component and includes a plurality of sensor groups. Each sensor group includes a plurality of magnetic sensors positioned to sense a magnetic field of one of the angularly spaced magnetic elements. Each sensor group generates a multi-state group signal in response to the passage of one of the angularly spaced magnetic elements. The processor circuit communicates with each of the sensor groups and generates position signals in response to the multi-state group signals.

Abstract: A continuous carpet (10) or other flooring manufacturing process that accommodates use of a variety of materials including recycled PVC from used carpet and carpet manufacturing waste. The continuous process forms backing (12) and is capable of feeding the backing into a lamination stage for bonding with the face cloth (14). By providing a continuous process whereby the backing layer, upon formation, can be immediately laminated to the face cloth, manufacturing time and associated cost are reduced. Moreover, formation of the backing layer as a process separate from the lamination thereby protecting the face cloth from unnecessary heat and pressure and enhancing the many types of material, including recycled and waste materials, especially used carpet and used carpet by products. Use of these cheaper materials reduces both the manufacturing cost by products.
