Abstract: A mechanical joint configured for providing dissipation of heat generated is provided. The mechanical joint includes a housing containing a motor assembly configured to drive a gear assembly for driving the mechanical joint, the motor assembly configured to be controlled by a control assembly for controlling rotation of a rotor of the motor assembly; wherein a brake disk of the control assembly is configured to increase air flow within the housing. A robot and a robotic system are also disclosed.

Abstract: A cable vent connector configured for venting an electric motor is provided. The cable vent connector includes an input for receiving a motor-side cable that includes a vent tube and a plurality of electrical conductors; a body configured for venting the vent tube to a local atmosphere, thus permitting an interior of the electric motor to reach pressure equilibrium; and a port for connecting the plurality of electrical conductors with a drive-side cable configured to drive the electric motor. A venting system and a production system are disclosed.

Abstract: A wind turbine includes a blade position adjustment system providing for continued wind turbine blade repositioning operation even after the occurrence of certain faults. The system includes a plurality of electrically operable motors, each of which is interconnected with one of the wind turbine blades to reposition that wind turbine blade and modify the blade pitch. Each motor includes two or more sets of electrically isolated windings, and a power supply is separately interconnected with each of the electrically isolated winding sets to provide for continued repositioning of each blade upon occurrence of a fault, such as voltage or current deterioration, in one of the winding sets.

Abstract: A heat sink comprises a base panel having a top surface and a bottom surface. A plurality of pin fins extend outwardly from the top surface and each fin has a cross-sectional configuration with two radiuses, a first radius and a second radius, wherein the first radius is larger than the second radius. The first and second radiuses are tangentially interconnected by intermediate portions, giving the pin fin cross-sectional configuration a raindrop shape, thereby generating low pressure drop across the heat sink by minimizing the drag force effects and maintaining large exposed surface area available for heat transfer.

Abstract: The present invention provides a simple and robust design implementing an easily accessible external terminal connection point for supplying drive current to an AC motor. An embodiment of the invention is directed to an insertion plug and a conductor formed within the insertion plug. Specifically, the conductor acts as a current bus through an insertion aperture defined in a motor housing. The interior end of the conductor acts as an interior connection terminal for an AC phase coil, whereas the exterior end of the conductor is configured to accept an external motor drive source power cable. Advantageously, the modularity of the insertion plug design and a modified insertion housing aperture stamping program provide significant flexibility with regard to placement of the connection terminal. This aspect of the invention allows the connection terminals, as well as a corresponding motor housing to be customized for pre-existing mechanical designs and assemblies.

Abstract: The present invention provides an apparatus that fastens elements of a frame assembly. The frame assembly implements fasteners as independent elements from both a housing and a corresponding housing cover. Exemplary embodiments of such fasteners may include the hook nut fasteners disclosed herein. Generally, such fasteners include a central portion providing a contact area disposed in the plane of a housing fastening aperture, an extension tab providing a contact area on a housing interior wall, and an extension block providing a contact area on a housing exterior wall. The extension block may include a hollow portion configured to receive a securing bolt. One advantageous application of the invention relates to automobile motor assembly housings. Specifically, in that embodiment the hook nut fastening assembly reinforces the motor housing and provides additional support to the assembly by reinforcing the joints between an end-cover and a motor assembly main body.
