sparcebag Posted February 7, 2009 Share Posted February 7, 2009 Whats the difference between a 12 volt and 24 volt! Does the 24 have a extra set of brushes? If so cant the extra set be removed and use it as 12 volt? They cant be much different than other electric motors,But I never had the opportunity to take a 24 volt apart Quote Link to comment Share on other sites More sharing options...
basstrebesch Posted February 7, 2009 Share Posted February 7, 2009 24 still only has two brushes i think it has more windings but not sure Quote Link to comment Share on other sites More sharing options...
BobT Posted February 9, 2009 Share Posted February 9, 2009 If you apply 12vdc to a 24vdc motor, chanes are you won't get the prop speed you need. Changing the voltage on dc motors is how motor speed is controlled.Using Ohm's law (E=IR) and Joule's law (P=EI) you would discover that applying a lower voltage to a resistance will result in lower current and therefore lower power. Basically the motor horsepower would drop and so too would torque.Bob Quote Link to comment Share on other sites More sharing options...
TonkaBass Posted February 9, 2009 Share Posted February 9, 2009 12v wont even get your prop spinning, at least not a 74pound. Quote Link to comment Share on other sites More sharing options...
DRH1175 Posted February 12, 2009 Share Posted February 12, 2009 Can you use 12v and 24v motors on the same boat? I currently have two batteries for my 12v motor. If I add a 24v transom motor can I still use the 12v with same batteries? Quote Link to comment Share on other sites More sharing options...
marine_man Posted February 12, 2009 Share Posted February 12, 2009 That depends on how your boat is wired, or how much work you want to put into it to make it happen.Is it a two wire setup or a four wire setup, as in, does each battery have it's own set of leads, or is the parallel connection made at the batteries?marine_man Quote Link to comment Share on other sites More sharing options...

It may be a bit of hassle to get wired up depending on your set-up. I think you could add a switch also to make it work. Quote Link to comment Share on other sites More sharing options...
marine_man Posted February 12, 2009 Share Posted February 12, 2009 I agree with your Pier... but the poster was wondering if he could run his 12v motor with the batteries in parallel...marine_man Quote Link to comment Share on other sites More sharing options...
sparcebag Posted February 12, 2009 Author Share Posted February 12, 2009 Seeing theres some attention here was my first answer correct?The windings make the diff between 12 & 24 V.Making it impossible to convert a 24 V to 12 or the other way.

Agreed... but drh1175 was effectively wondering if you he can run his two batteries in parallel and series at the same time. Which, unless you have a 4 wire plug I don't think is possible.marine_man Quote Link to comment Share on other sites More sharing options...

Sorry Sparce... I have no idea.marine_man Quote Link to comment Share on other sites More sharing options...
DRH1175 Posted February 12, 2009 Share Posted February 12, 2009 I think I can according to the diagram. Thanks! If I run the 12v off 1 battery and use the 24v using two in series it will work! Right now I have them Parallel to use the 2 batteries for my 12v bow mount. I want to get a vantage trolling motor for the rear, but they only come in 24 and 36 volt versions. I don't want to have to sell the 12 and purchase a new 24v bow as well. Quote Link to comment Share on other sites More sharing options...
DRH1175 Posted February 12, 2009 Share Posted February 12, 2009 Sparcebag, do you have a 24v? What is it? [note from admin: please read forum policy before posting again. thanks!] Quote Link to comment Share on other sites More sharing options...

Yes, this will definitely work. The way I interpreted your first post you wanted to run the 12V with parallel batteries... hence my response.marine_man Quote Link to comment Share on other sites More sharing options...
