  • Patent number: 8025250
    Abstract: Length equalization may be provided. First, a plurality of conductors may be paid off from a plurality of pay-off devices respectively corresponding to the plurality of conductors to form a cable. The plurality of conductors comprising the cable may then be wound onto a take-up device. During the winding process, a guide device may be rotated to cause the plurality of conductors to have substantially a same length after the cable has been wound onto the take-up device. The guide device may be disposed between the take-up device and the plurality of pay-off devices. The guide device may have holes respectively corresponding to each of the plurality of conductors. Each of the plurality of conductors may pass through a respective hole in the guide device.
    Type: Grant

  • Publication number: 20090091301
    Abstract: An operating system for an electric motor associated with a hydraulic pump for moving a load and method of operating the same. The operating system includes a power source that is electrically connected to the electric motor wherein a capacitor charge and discharge circuit is used in association with a capacitor in order to store energy within the capacitor as the operating system is in use.

  • Publication number: 20070053780
    Abstract: An electro-hydraulic power unit with an improved hydraulic fluid flow through the unit. The unit accomplishes the improved fluid flow by having an inlet port in a housing that is fluidly connected to an electric motor that has a rotor with vanes cast thereon and at least one opening within the rotor. A hydraulic pump inlet is fluidly connected to the electric motor such that the vanes of the electric motor will supply hydraulic fluid to the hydraulic pump inlet.

  • Publication number: 20050178117
    Abstract: A charge pump is provided with two independent outlets that can satisfy the pressure requirements of both a charge circuit and an auxiliary circuit. Preferably, the charge pump is a multiple roller vane pump that has at least one inlet and two outlets independent of each other. The first outlet is in fluid communication with a charge circuit, and the second outlet is in fluid communication with an auxiliary circuit. Because the two outlets are independent of each other, the roller vane pump is able to satisfy the pressure requirements of both the charge and auxiliary circuits. Preferably, the two outlets are diametrically opposed to each other, thereby reducing the load on the driveshaft. Additionally, the roller vane pump may include a second inlet independent of the first.
