Lawnmower Power Generator With A Twist
nice i have make it too but micro size 24v 50A met auto start en water cool system alles is automatic druk op de startknop dan start het al binnen par seconde acht handig
My former position,before retirement,was at Briggs and Stratton as a engine/ power train design engineer I guess lends nothing then...Not!!!Tecumseh,Briggs and Stratton,Wisconsin,Milwaukee,and Kohler all utilized what I had mentioned for the point of engine balance,but on newer engines that are vertical shaft,the newer flywheels although Aluminum still require the blade and adapter for the purpose of engine balance...As far as your statement of "but is more dependent on whether or not the engine is internally balanced. ",All engines are internally balanced to a degree because of the crankshafts on all engines have counterweights,or balanced crank wheels,(as in a Harley engine),but still require more to balance them to reduce bearing and seal wear......i.e. Vibration dampener on the front of a car engine... - StevenS178
With every respect, that is simply not true. It depends greatly on type of engine used yes, but is more dependent on whether or not the engine is internally balanced. 99% of all of these OPE engines are, which means as long as it has some load at the crankshaft/pto end of the engine, it'll be fine. Type of flywheel is irrelevant in this case, as a common retrofit for older engines to gain performance (ie above rated rpm output) is to convert with an aluminum aftermarket flywheel. In the case of what the author has suggested, this setup is fine. - FatboyD
An Easy to build generator,but one thing that the author didn't consider...Since the engine came off a lawnmower,(Vertical shaft), it has an aluminum flywheel and the engine needs the blade and blade adapter on it for the engine to be balanced...Without those components the engine will fail prematurely...A side shaft ,(or Hortizontal),has a cast steel flywheel which keeps the engine balanced...So my recommendation would be to use a "Hortizontal shaft engine for longevity and reliability...
Okay, great idea, but I see some basic facts I would like to clarify. You are using an alternator, which creates AC power (Hence the name; originally cars used DC generators but switched for better efficiency). All modern alternators also contain a rectifier which changes the AC generated by the alternator into DC. Then you are taking the DC output of the alternator and inverting it back to AC. Each time you change from one to the other you lose efficiency; i. e. available power. So instead of an alternator why not use an AC motor? A motor and a generator are identical; one produces mechanical energy when power is applied and the other produces AC power when the shaft is mechanically spun; so use the engine to spin the shaft of the motor and voila! you will produce AC current. Now you will need a voltage regulator, however you will NOT need an inverter; And you will be able to produce much more power at a better efficiency; also your choice of motors are near endless; old washing machine motors come to mind among dozens of other low cost options. Varying pulley sizes can attain proper rotational speeds. People already use old motors for power generation by attaching blades to the shaft and using wind to turn the motor. Search the internet and you will find a multitude of articles on how to use an old motor to produce electricity; combine that with the old lawn mower concept and you will have dozens more available options to produce much more power.
