20150236630 | VOLTAGE REGULATOR SYSTEM FOR A GENSET - A voltage regulator system for regulating an output voltage of a genset includes a voltage regulator for reducing terminal voltage in response to a reduction in terminal frequency. A plurality of under-frequency roll-off (UFRO) states is provided in the voltage regulator, with each UFRO state being configured to implement a UFRO characteristic. An operational signal indicative of an operating condition of the genset forms the basis for selection of the UFRO characteristic. | 08-20-2015 |
20150207383 | BASE FOR A GENERATOR - A generator assembly may include a base made of a composite material for supporting a plurality of components including an alternator, and engine, and a fuel tank for storing the fuel for the operation of the engine. The base may include a recess formed in a support surface of the base, and a lid configured to be detachably mounted to the support surface to close the recess and form the fuel tank. The lid may include a baffle configured to extend into the recess and separate and define a fuel feed chamber and a return flow chamber in the recess. | 07-23-2015 |
20150181735 | ENCLOSURE FOR A GENERATOR - An enclosure is provided which is mountable to a base frame carrying a generator. The enclosure includes a lower portion connectable to the base frame. The lower portion includes a lower first sidewall, a lower second sidewall, and a lower first end wall and a lower second end wall. The enclosure further includes an upper portion having a roof, an upper first sidewall, an upper second sidewall, and an upper end wall depending downwardly from the roof. The lower portion and the upper portion are hingedly connected together such that the upper portion is pivotable relative to the lower portion between closed and open positions. | 06-25-2015 |
20150176751 | BASE FOR A GENERATOR - A base made of composite material is configured for supporting a generator. The base may experience some vibrations transferred from the generator. The base may include one or more mounting members to secure the generator to the base. The mounting members are located at least partially over each of a plurality of access pockets provided in the base. The mounting members are arranged over the access pockets to provide an access to the underneath of the mounting member. | 06-25-2015 |
20150152996 | BASE FOR A GENERATOR - A base made of a composite material supports a generator assembly. The base may support a number of components of the generator assembly, including an alternator, an engine, a control panel, a fuel tank, and a lifting frame. The base may include first and second tiers that are in two different horizontal planes for mounting of the alternator on one tier and the engine on the second tier, with a drive shaft of the alternator being aligned with a drive shaft of the engine. The base may include ribs extending from an under side of a support surface of the base in order to distribute loads and withstand stresses that result from the weight of the generator assembly. | 06-04-2015 |
