Abstract: A system is provided including a current sensor arranged to sense current drawn by an electric motor of a powered device through an AC power line from a power supply and provide current data related to the powered device; a monitoring device arranged to receive the current data from the electrical sensor, the monitoring device including a controller processing the current data to obtain performance data associated with the powered device, the performance data relating to load applied to the electric motor; a data communication device communicating with the monitoring device and arranged to receive the performance data associated with the powered device; and a computing device including a graphical user interface, the computer device receiving a user's selection of the powered device from a list of powered devices and presenting the performance data to the user via the graphical user interface in response to the user's selection.

Abstract: A traction drive system includes an endless member having a coupling couplable to a vehicle. A pair of rotating wheels support the endless member for rotation in a closed path. A drive assembly includes at least a pair of counter-rotating drive wheels wherein the drive wheels of the pair of counter-rotating drive wheels are disposed on opposite portions of the endless member to apply a driving force thereto. Each drive wheel is operably coupled to a drive motor.

Abstract: A rod end has a split clamp housing which supports a bearing for transferring motion or loading forces from an actuator to another part to be loaded. An adjustable stop for the clamp is used to adjust the backlash of the bearing used with the rod end to a desired level without causing distortion. A spherical washer set is used for transferring loads between the two clamp portions. The housing for the bearing is clamped against the spherical washer set at a preselected loading so that the bearing is able to rotate and swivel as needed, but backlash is removed.

Abstract: An armature adapted for use in a voice coil or linear motor and having a conductor winding and at least one stiffening layer coaxial and coextensive with, either inside or outside, the conductor winding. The stiffening layer is formed of a multiplicity of turns of a high elastic modulus, non-magnetic fiber such as graphite. The fiber and conductor turns are all firmly bonded into a rigid, composite unitary cylinder by a substance such as epoxy impregnating the entire composite cylinder. In a preferred embodiment, the conductor turns are located between interior and exterior layers. In a preferred method for manufacturing such an armature, the composite cylinder is formed layer by layer on a rotating mandrel, impregnating each layer with epoxy resin premixed for self-hardening.
