Universal motor...
Posted: Fri Oct 19, 2007 10:13 pm
Hi all.
A long time ago, I read a very good and simple technical explanation why a plain 120VAC circular saw motor is perfectly capable to perform very well with 12V DC, and the proof from the writer; an electric bicycle he made with a 'Skil' saw and a car battery... or two.
Can someone explain the principles of similar POWER capabilities with such different voltages? Cannot find now the article on the net explaining it.
A circular saw is not among my toys, or I would have already tested with 12V DC to compare its POWER.
Thanks,
Miguel
