One is Peak Cranking (you will see most above 600 amps), this is what a car needs to turnover the starter and it does not need this for more than a few seconds and it does not mean much to telescope equipment. Well I was figuring the guy in the OP just hooked the 12V battery to the furnace AC input - this would mean the motor was powered through the controller. What's the capacity of your power source in mAh? In this white paper learn how a standards-based, systematic, and automated generative MDD/XIL workflow helps automotive engineers develop their production ECU Verification & Validation (V&V) suites early during software modeling, and reuse them throughout the overall systems engineering project. The heater blower motor in your car is designed to run on 12 volts. 12V vs 18V: what can 18V do that 12V can't, not just including drills I'm looking at picking up a chordless drill soon. But if you happen to have 18V for whatever reason, you can always use a DC-DC converter. This whitepaper examines common DVE challenges and some promising solutions. Since 12V lead-acid batteries were originally designed for cars, there is a lot stuff that runs this way. As an example my water cooled fridge compressor uses a 24 volt pump, running on 12 volts, becase that is quieter than a 12 volt pump running at full speed. This white paper reviews market trends that are transforming embedded software development in the automotive industry. These applications include on-card regulation for elimination of noise and distribution problems associated with Only about 10 cycles per hour, an hour a day. You do not have to split it, just supply 12V to the power connector on the Arduino board, it will take what it needs. This makes it easy to measure the life in a battery by simply measuring its voltage. If you were to run a 12v motor off a 24v battery the stall current could then be excessive if it weren’t limited by the controller. From TI's datasheet: https://www.sparkfun...ents/LM7805.pdf. If the motors demand too many amps the driver ICs can fail. This eBook addresses the missing links that determine success or failure in Digital Transformation and shows how organizations can build a sustainable path forward, with fewer resources, in less time, and with better outcomes. If you still can not find the information you will need to buy an amp meter and take readings on your equipment. Like most string trimmers, you need to install the guard. Re: Using 18V cordless tools on 24V battery bank I am aware of the over charge/discharge considerations of Lead acid cells. The same thing will happen with a 24 volt motor with 12 volts applied. That's what's going to heat you up and burn you out. A battery would also typically have a maximum amps it could deliver continuously before the terminals melt, but most electronics wiring will melt before that. It'll just run slower. So fusing is needed to protect them. "12 volt" batteries really run between 11.5 and 14 or so. Running it at 18V is a very bad idea. Registration is simple and free and removes most advertising. I've used a 9v drill with a 12v … That would be when both drives were slewing. Questions for OP. 99. The standard voltage regulator is the LM7805 that delivers 5vDC or ta a similar 3.3 volt regulator.

Is there any disadvantage to the SVBONY SV205 for lunar photography? I suspect, given the mass of the motor and the industrial application of it's first purpose, that it would propably be fine but given the feedback I will leave well enough alone. If I attached a 12v 10a PS and the motor was rated 12v 5a, what would happen? 12V is well under this and … "12V panel" means 18 volts. You contact the companies if the readings are not in the specs or you post your equipment and ask other owners. Whole thing is to operate a 1 inch bore RAM. single-point regulation. Already a Member? You must register before you can post: click the register link above to proceed. One neat feature of the LX200 was an amp meter, Not sure how accurate it was, but you could see the draw as it went through its paces. There is no amp hour rating for equipment, only amps. If in fact this is a 12/24 volt 4spd or 5spd it will not make a difference. Your solar panels are rated to a maximum output of 3.5 amps at 18 volts which is 63 watts. They have thermal protection and will shut down if they overheat. Running it at 18V is a very bad idea. It will work fine on 12V. would it be possible to start the motor at 12V and then gradually increase it to 18V? The L293D driver used by the Nexstar GPS can only handle 1 amp. For example, a nominal "18V" NiMh battery could be 15 cells, when fully charged it might be 21V and fully discharged 15V. They are rated for 12V, but their duty cycle is very low. Already a member? Is there any advantage to using a higher voltage battery to power lower voltage equipment? Can I hardwire from this power-supply to my 18v cordless drill, without damaging the extra voltage damaging the drill? Maybe you could hook up a potentiometer to dial up the power as needed? Registration on or use of this site constitutes acceptance of our Privacy Policy. However, you could most likely run the same motor indefinitely at 3V. I will attach the motor to a 12v battery this weekend and check the amps so I can choose the right PS. What is the free running current of the motor? Cause of concern or intentional. I have 110v power nearby, but do not want to run 110v to the water's edge for safety reasons. Use Upwork to chat or video call, share files, and track project milestones from your desktop or mobile. To start viewing messages, select the forum that you want to visit from the selection below. The over-voltage will allow the motor to draw more current. Providing the motors with higher voltages will drop the amperage required for them to do their work. Therefore, provided you chose a controller suitable for the motor you use, you can usually run a motor 12v motor from a 24v battery with no effect except that full speed is doubled. Bad idea I think - likely to fry various components not wired for the higher voltage. Please re-enable javascript to access full functionality. Just wondering how long it will take your motor to overheat! 11 years ago. If you connect a 12v device to an 18v power supply, you stand a good chance of letting the little bit of smoke escape. Makita 9.6V drill motor and Honda Accord wiper motor run from 12V 10A power supply ($12.50). I use car-plug type adapters for all my 12v equipment because they have fuses in them. When it's hot the voltage regulator may overheat. When a lower speed is selected, a resistor is placed in series with the motor, thus reducing its voltage. no electronics other than a coil relay to close the motor circuit. *Eng-Tips's functionality depends on members receiving e-mail. Re: Can you run a 24V motor on 12V battery? Used to have ammeters in autos, too. Even though it is "an hour a day", it is still 10 starts per hour. Yes - the advantage is that you'll blow up all you're equipment and then the battery will last a very long time. Tags: ... this gives the ability to vary the speed efficiently. Seems like you've entered the realm of trial and (hopefully no) error. Most equipment rated for 12V is spec'ed to run between about 11 and 14 volts. Login. I was thinking of using an old dual battery charger and gutting it. Let's take a step back for a moment and find out what type and model trolling motor this is. The "starting" action, with it's inrush current, does all the damage. (or whatever in between). PWM Motor Speed Controller 5V 9V 12V 18v 24V 30V DC 5V-30V Pulse Width Modulation Regulator 5A 150W Stepless Variable Speed/Forward and Reverse Switch Pulse Width Modulation DC Speed Regulation.

Join your peers on the Internet's largest technical engineering professional community.It's easy to join and it's free. I think Walterke has it right. So we can assume they never expected it to need more than two amps when it was drawing the maximum current. A larger motor is not really an affordable alternative because the pump and motor are one assembly. In general you should look at the equipment specifications to see what they recommend. DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging, Community Forum Software by IP.BoardLicensed to: Cloudy Nights, This is not recommended for shared computers, Help - In Need of Crash Course in Planetary Imaging, Quark Chromosphere and Orion 120ST... trying to make it work. That means you will use a total of 48 amp/hrs, you should never use more that 50% of the battery capacity (some say 30%) so in this case it is 48 amp/hr times 2 = 96 amp/hrs should be the rating of your battery. Please let us know here why this post is inappropriate. Ok then, how about amps rating? They work fine, although as mentioned below they are somewhat weaker. By joining you are opting in to receive e-mail. Worse case scenario, you go back to 12V and/or buy a new motor!! As long as the battery can deliver the minimum required for the device, you're good to go. The risk and cost of failure is quite high, though, so you probably wouldn't take the chance. There are a few items that would work better with an 18 volt battery but the equipment will specify if it is OK.  One example is Losmandy GM-11 and GM-8 mounts (also a number of mounts that Losmandy built for other companies). the motor operates a hydraulic pump. i would still just wire the relay 12 volts. The guard is easy enough – just slip it over the metal protrusion and use your winged bolt to tighten it down. The time savings won't be enough to warrant "trial by smoke". 7.5.5.4 with Teamcenter 8 on win7 64Intel Xeon @ 3.2GHz8GB RAMNvidia Quadro 2000 TygerDawgBlue. 12V motor of the motor to draw more current always keep a of...
