Would undervoltage kill a trolling motor (24 volts DC battery)?

Would undervoltage kill a trolling motor (24 volts DC battery)? would it kill my digital wireless controlled trolling motor (designed to run on 24 volts) when hook up to a 12v battery?
I heard different story about this. Can somebody explain and thanks in advance? I just bought a digitally wireless motorguide 75 pounds big trolling motor and didn't want to ruin this nice big motor by doing some silly things. My TM does have a control board to steer the motor. I am new to the RC world, and I have a smaller hand controlled TM 30 pounds and would like to set it up for my canoe so I can control it wirelessly. So, I bought a wiper motor (reversible) to hopefully somehow come up with a mechanism to steer it wirelessly. Any suggestion about how to do about this? Why? I want to kill 2 birds in 1 shot, just in case my big 75 pounds control board breaks, I can easily figure out how to build a IC board to get it to run again. Motorguide don't sell this board anymore, so if it breaks I am out of luck! Thanks. http://www.rcuniverse.com/forum/atta...mentid=2193111 |
Reducing the voltage to the motor will usually just reduce performance. Reduced voltage to a control board is unlikely to damage the board, but might not let it work. It all depends on the design.
Beware of the word "digital" when it appears in advertising for consumer goods. It has become a fairly meaningless marketing buzzword to be used if there is an integrated circuit in there somewhere. |
why didn,t you buy a 12 volt powered Motorguide motor as the 24 volts motorguides are a pain having to use 2 x 12 volts batteries. i have a the largest 12 volt motorguide and it supplies ample power to mt 5 meter side consol tinny. if you run 12 volts into a 24 volt motor circut you will lose approx half the power output. its like running a 6 volt battery in a 12 volt car.

buddy of mine used a power seat drive from a buick, it was a worm drive with 12 volt motor attached a little slow but it worked

[ Got RPM ] Oh dear god i am terribly sorry for giving an incorrect answer to a simple question, please forgive me my son as i did mean well . you didn,t have an answer to this question sir ? have a nice day.

About running your motor on 12 volts. The general rule with motors and speed controls is the higher the voltage the lower the amount of current you will draw. So in theory, yes I would imagine a system designed to run on 24 volts might not be able to handle the increased amps it would draw at 12 volts. But it would not affect the motor, it would be the speed control that would take the hit.

The above is simply inaccurate. With the same load (prop), reducing the voltage reduces the amp drawn. The opposite is where most folks get into trouble.

If you want to reduce current draw but keep the same power, you increase the voltage and use a higher voltage motor of the same general size but with different windings. The only iffy parts about running a system on a lower voltage is if there is an electronic control board involved, which might not perform properly on a reduced voltage, and the motor might not start reliably with reduced torque. |
