Abstract:

A single axis driving system includes a housing with a central portion defining a cavity and a pair of parallel spaced apart flanges formed as an integral part. Coaxial openings are formed through the flanges to define a mounting structure for an axel rotatably mounted in the coaxial openings. An opening is formed between the flanges in the surface of the central portion extending into the cavity. A gear plate is affixed to the axle and positioned to extend through the opening into the cavity for limited rotation with the axle. The gear plate has an arcuate set of gear teeth positioned along a periphery thereof. A driving gear is rotatably mounted in the housing so as to mesh with the arcuate set of gear teeth and a drive motor is mounted on the housing and attached to the driving gear for rotation of the driving gear.

International Classification:

H02S 20/32
H01L 31/042
G05D 3/10

Abstract:

A single axis tracker system including at least one photovoltaic panel, a mounting structure, and a tracker control system. The tracker control system being attached to the at least one photovoltaic panel and to the mounting structure so as to apply torque to the at least one photovoltaic panel to rotate the at least one photovoltaic panel into an allowable orientation. A wind tracking device is coupled to the single axis tracker system and connected to the tracker control system. The wind tracking device determines current wind speed and direction information and couples the wind speed and direction information to an algorithm in the tracker control system. The algorithm uses the wind speed and direction information to calculate an allowable photovoltaic panel orientation for the current conditions.

Abstract:

A distributed torque, single axis solar tracking system includes a plurality of spaced apart mounting posts with selected posts having an electrically controlled actuator mounted thereon. A torque structure extends between the actuators to distribute rotational torque on the torque structure. A plurality of solar panels is connected to the torque structure. Electrical apparatus is coupled to each actuator and designed to be coupled to a power source so that when the electrical apparatus is coupled to the power source, the plurality of actuators is energized to rotate simultaneously a desired amount. Whereby the plurality of solar panels is rotated the desired amount as the plurality of actuators rotates.

Abstract:

A gear assembly diagnostic system includes an electric motor attached to a gear assembly to be diagnosed, a motor controller coupled to the electric motor to control electric current applied to the electric motor, a test controller coupled to the motor controller to provide commands to the motor controller, and electrical current determining apparatus coupled to provide a measurement of current flow through the electric motor. A programmable data acquisition device is coupled to the electrical current determining apparatus and is programmable to determine current flow through the electrical motor at a predetermined frequency. Data storage is coupled to the data acquisition device for receiving and storing current flow determinations from the data acquisition device and a computer is coupled to, and may include, the data storage. The computer includes software designed to calculate one or more characteristics of the gear assembly to be diagnosed from the current flow determinations.
