As a core rotating component of the generator's electrical system, the rotor works with the stator to produce the AC current that powers onboard electrical loads, so a worn or failed rotor can lead to weak, inconsistent, or absent generator output. This rotor is built to restore original generator performance and is manufactured with a machined exterior finish for accurate fit and reliable operation in the marine environment.\u003c\/p\u003e\u003cp\u003eThis part is designed to fit a wide range of Westerbeke generator models across the BEG, SBEG, BCG, BCGA, BCGB, BCGC, and BCGTC series, covering both 60Hz and 50Hz configurations from 4.5 kW up through 15.0 kW output ratings. Because Westerbeke generator model designations vary by kW rating and configuration suffix, boat owners and technicians should confirm their specific generator model designation against the fitment list before ordering to ensure this rotor is the correct match.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
