Lister Based Generators / Alternator Hz tip
« on: June 23, 2019, 11:02:10 AM »
I heard a suggestion for fine-setting of engine speed to obtain the required Hertz.
Assuming pulleys of theoretically near-correct ratio are installed on engine and alternator shafts:
Paint a white line on the alternator pulley, so that with a lamp shining (powered from grid, on a house circuit for example) the line will appear stationery when correct speed is achieved.
It's the same principle that was often seen on hi-fi record player turntables.
Has anyone else heard of this method?
