In one embodiment, a generator includes a rotor configured to rotate in cooperation with a stator to generate electrical power. A sensor, which is supported by the rotor, is configured to generate a trigger signal indicative of a position of the rotor. A communication interface is configured to receive the trigger signal from the sensor of the rotor and receive data indicative of an output of the generator. A controller supported by the rotor or configured to perform a phase analysis of the trigger signal and the output of the generator and calculate a power angle for the generator based on the phase analysis.

Alternator controller

An apparatus and method for providing electrical insulation between adjacent end turns at different phases within a stator assembly. In one embodiment, the invention is directed to a stator assembly comprising: a stator core; at least two coils of different phases wound on the stator core through the slots and having an end turn that extends from the stator core; and one or more rigid separator members positioned between adjacent end turns of the coils.

Power angle calculation for alternator controller

An apparatus and method for providing electrical insulation between adjacent end turns at different phases within a stator assembly. In one embodiment, the invention is directed to a stator assembly comprising: a stator core having a plurality of slots; at least two coils of different phases wound on the stator core through the slots and having an end turn that extends from the stator core; and one or more separator members positioned between adjacent end turns of the coils.

A method and apparatus are disclosed for preventing damage to an alternator of a genset resulting from high currents within the alternator. The method includes calculating, at a processor, a first quantity related to a current flowing through the alternator during a first time period, and comparing, at the processor, the first quantity with a first threshold. The method further includes calculating, at the processor, a second quantity related to the current flowing through the alternator during at least one of the first time period and a second time period, and comparing, at the processor, the second quantity with a second threshold. The method additionally includes indicating a current overload condition if at least one of the first quantity exceeds the first threshold or the second quantity exceeds the second threshold.

Method and apparatus for preventing excessive heat generation in a alternator of a generator set

A rotor for use in a generator or a motor wherein damper bars extend through rotor laminations and at least one of the damper bars extends from the laminations to provide support for a coil portion. In a preferred manner the damper bar extends from opposing ends of the laminations.

Rotor

A compact generator unit including a cooling system in which the engine and generator are mounted at points outside of the perimeter of the generator fan such that the generator fan serves to cool both the generator and the engine.
