Machine having electrical power system and method
First Claim
1. An electrical power system for a machine comprising:
- a generator configured to generate electrical power for said machine, said generator having a speed range that includes a resonance speed associated with resonance vibrations of said system;
an engine configured to rotate said generator; and
a drive coupling having a first element fixed to rotate with said engine and a second element fixed to rotate with said generator, said first and second elements being configured to rotationally couple together for transmitting torque from said engine to said generator, said drive coupling being further configured to allow relative slip between said first and second elements when said generator is rotated at said resonance speed.

Abstract
A machine and electrical power system includes a generator having a speed range that includes a resonance speed associated with resonance vibrations of the system. A drive coupling is disposed between the generator and an engine configured to rotate the generator and is further configured to transmit torque from the engine to the generator, the drive coupling being configured to allow relative slip between first and second elements when the generator is rotated at its resonance speed. A machine operation method includes rotating a generator with an engine, and generating resonance vibrations of at least one of the engine and the generator by rotating the generator at a resonance speed. The method further includes inhibiting transmitting resonance vibrations between the generator and the engine by allowing relative rotational slip within a drive coupling disposed between the engine and the generator.
