Patent application numberDescriptionPublished
20140266300PHASE-CHANGE MATERIAL RECONFIGURABLE CIRCUITS - One embodiment of the invention includes a reconfigurable circuit comprising a phase-change material switch. The phase-change material switch includes an actuation portion configured to receive a control signal having one of a first state and a second state and to emit a first heat profile in response to the first state of the control signal and a second heat profile in response to the second state of the control signal. The phase-change material switch also includes a switch portion comprising a phase-change material in proximity with the actuation portion. The switch portion can be selectable between a conducting state in response to the first heat profile to conduct an input signal from an input to an output of the phase-change material switch and a blocking state in response to the second heat profile to substantially block the input signal from the input to the output.09-18-2014

20140102674RADIALLY EMBEDDED PERMANENT MAGNET ROTOR AND METHODS THEREOF - In one embodiment, a permanent magnet rotor for use with a stator is provided. The permanent magnet rotor includes at least one permanent magnet and a substantially cylindrical rotor core including an outer edge, a hub having an inner edge defining a central opening, and a plurality of independent pole pieces spaced from the hub radially about the central opening. The rotor core further includes at least one radial aperture extending radially from the outer edge through the rotor core between adjacent independent pole pieces, the at least one aperture configured to receive the at least one permanent magnet.04-17-2014
20140103769RADIALLY EMBEDDED PERMANENT MAGNET ROTOR AND METHODS THEREOF - In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a shaft comprising an outer diameter, a first hub coupled about the shaft outer diameter, and a first plurality of pole pieces positioned radially about the hub. The rotor further includes a plurality of permanent magnets positioned radially about the hub. The plurality of pole pieces and the plurality of permanent magnets define a rotor outer diameter, and the rotor outer diameter is magnetically isolated from shaft.04-17-2014
20140103772RADIALLY EMBEDDED PERMANENT MAGNET ROTOR AND METHODS THEREOF - In one embodiment, a permanent magnet rotor is provided. The rotor includes at least one permanent magnet and a substantially cylindrical rotor core including a plurality of stacked laminations, a hub having an inner edge defining a central opening, and a shaft inserted through the central opening, the shaft magnetically isolated from the hub. The rotor includes at least one connected pole piece coupled to the hub and at least one independent pole piece separated from the hub. The at least one permanent magnet is disposed between the at least one connected pole piece and the at least one independent pole piece.04-17-2014
20140265748ELECTRICAL MACHINES AND METHODS OF ASSEMBLING THE SAME - A housing for enclosing electronics of a motor having an axis of rotation is provided. The housing includes an end cap having an outer surface and an inner surface. A control board is coupled to the inner surface, wherein the printed circuit board includes a first side, a second side and an edge located between the first side and the second side. The housing further includes a first circuit coupled to the first side which includes a plurality of first electrical components. Each first electrical component includes a tab extending beyond the edge. A second circuit is coupled to the second side and a fastener assembly is coupled to the tab and the inner surface.09-18-2014

20150061441ELECTRIC MACHINE AND ASSOCIATED METHOD - An electric machine includes a machine housing and a stator disposed at least partially within the housing. The electric machine also includes a radially embedded permanent magnet rotor disposed at least partially within the housing and an endcap. The rotor has at least one radially embedded permanent magnet that is configured to provide increased flux to reduce motor efficiency loss. The endcap is operably connected to a distal portion of the rotor.03-05-2015
