If it is designed to work with 12V panels it will work with your panel. Tags: ... this gives the ability to vary the speed efficiently. Makita 9.6V drill motor and Honda Accord wiper motor run from 12V 10A power supply ($12.50). As long as the battery can deliver the minimum required for the device, you're good to go. the motor operates a hydraulic pump. The only problems you may have are if the motor takes such a big current that the voltage drops too low to supply the Arduino. If I had gotten a concenses here that given the duty cycle / application it wouldn't be a problem I would have gone ahead but obviously there are two many variables. This is NOT the case with voltage, as has been pointed out. I fish with the electric mostly and the main motor doesn't run enough to keep up with the drain from electronics and accessories. No tools required. This white paper reviews market trends that are transforming embedded software development in the automotive industry. They are rated for 12V, but their duty cycle is very low. If the smoke is allowed to escape the device will no-longer work. The motor will take a higher voltage most of the time, but will heat up more and wear out much faster. "12 volt" batteries really run between 11.5 and 14 or so. Providing the motors with higher voltages will drop the amperage required for them to do their work. You contact the companies if the readings are not in the specs or you post your equipment and ask other owners. 3. not very long by the sounds of it. There is no amp hour rating for equipment, only amps. Can I hardwire from this power-supply to my 18v cordless drill, without damaging the extra voltage damaging the drill? The L293D driver used by the Nexstar GPS can only handle 1 amp. 1) You can physically remove the 220V motor that you have and replace it with a 12V motor of the same size. Imagine a starter motor for your car. Maybe you could hook up a potentiometer to dial up the power as needed? I will attach the motor to a 12v battery this weekend and check the amps so I can choose the right PS. Already a Member? We need a battery that will supply amps for as many hours as possible. If you goose it with +50% voltage, 10X per hour, expect failure over time. $13.99 $ 13. Already a member? This would cause the Arduino to black out and reset momentarily. Meade introduced the LX200 in 1992 rated for 12v. Worse case scenario, you go back to 12V and/or buy a new motor!! single-point regulation. You’ll need the hex wrench to connect the shaft in the center. For Now I have this 12v motor and a 24 V, 6.5 A Switching powersupply. As Billydee explained, add up the nominal average current draw from all your devices to be run from the battery (in amperes at 12 volts), multiply by how long you want to be able to run (in hours), double that and then choose a battery with at least that rating of amp-hour capacity. Just wondering how long it will take your motor to overheat! This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. Seems like you've entered the realm of trial and (hopefully no) error. Bad idea I think - likely to fry various components not wired for the higher voltage. Please let us know here why this post is inappropriate. "12V panel" means 18 volts. If you run it at 12V for a minute you better look for a new starter. But if you happen to have 18V for whatever reason, you can always use a DC-DC converter. Run a 220V to 250V AC Washing Machine Universal Motor of 1 H.P at JUST 12V DC from UPS Battery with Full Explanation, Wiring, and Connections . Also, running a battery hot will drastically reduce its lifespan, and running it really hot is very dangerous. :) Thanks for the feedback. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. The 18V to USB adapters that RIDGID and others have for sale got me thinking about a 18V to 12V down converter that could power some high amperage 12V DC equipment. I think Walterke has it right. For example, a nominal "18V" NiMh battery could be 15 cells, when fully charged it might be 21V and fully discharged 15V. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. 11 years ago. It isn't just the voltage on the DC motor that you have to worry about. no electronics other than a coil relay to close the motor circuit. 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. When a lower speed is selected, a resistor is placed in series with the motor, thus reducing its voltage. I know my supply is a lot higher for the motor to take but i want to try using it, At first i tried Directly hooking my motor to 24v power supply out of curiosity, the motor runs for 2seconds and the power shuts down and turns on … 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. Try it and see if it works. The standard 12 volt battery is really a 13.4 volt battery and they all work that way. When used in mount drive circuits the input voltage that goes to the motors and the driver ICs is generally not regulated. Whenit's cold the waste heat will help keep the electronic warm enough to operate properly. I understand it would generate more heat. Only about 10 cycles per hour, an hour a day. 2) You can't. Thanks desertfox. 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.

This whitepaper examines common DVE challenges and some promising solutions. I assume you do not have any definitive info from the manufacturer about higher voltage operation and acceptable quantity of starts/hour. Once you've done this replacement, you'll need much larger power wires, assuming you want the same torque. Cause of concern or intentional. I recently bought a hybrid inverter, Luminous NXG 750 which according to their technical specifications (attached image, highlighted in red), supports solar panel of 12v upto 400wp. An HT might last a couple days. I was thinking a dual port charger using a pair of 4 or 5 AH 18V batteries should be capable of 5 or 6 amps at 12V which would run a mobile rig on low power TX for a good period of time I would think. It'll just run slower. Buy RS-550s 18v (12v - 20 volts) DC Motor Round Shaft - High Power & Torque for DIY Electric/Electronic Projects, Drills, Robots, RC Vehicals, Remote Controlled Cars/Robot, Saw Repair/Replacement Engine: Fan Motors - Amazon.com FREE DELIVERY possible on eligible purchases Several functions may not work. I don't recall seeing that in manufacturers' specs. I'm thinking of powering equipment like a 35 watt GMRS radio. 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. Your electric motor … 18 volts dc through a 12 volt dc motor. You currently have javascript disabled. Let's take a step back for a moment and find out what type and model trolling motor this is. The time savings won't be enough to warrant "trial by smoke". Re: Can you run a 24V motor on 12V battery? So fusing is needed to protect them. The same thing will happen with a 24 volt motor with 12 volts applied. Re: Using 18V cordless tools on 24V battery bank I am aware of the over charge/discharge considerations of Lead acid cells. 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. What is the free running current of the motor? Running it at 18V is a very bad idea. I have a power supply with unused 18v outputs on the way so I'm wondering if I could/should run some of my analog pedals at 18V since I've read I can get more headroom. In fact this is what a fuse is designed to do. I have run 18 volt, 14 volt, and even nine volt battery tools for years on twelve volt car batteries. Tell us what you need. For example, using an 18v battery to power 12v equipment. Currently uses a rep cycle rv battery. Is there any disadvantage to the SVBONY SV205 for lunar photography? Even little computerised things like microcontrollers (in small GOTO mounts) which might be regulating 12V down to 5V or so - the regulators may overheat leading to unreliable operation if left running for more than a few minutes. As far as amp ratings go. This smoke is necessary for the functioning of the device. It will work fine on 12V. 50% over is NOT small. 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. You do not have to split it, just supply 12V to the power connector on the Arduino board, it will take what it needs. These applications include on-card regulation for elimination of noise and distribution problems associated with An analogy: You can probably safely move 12 tons across a bridge rated for 10. Every device has a little bit of smoke added at the factory. You need to add up all your equipment amps per hour rating and then purchase a good battery that will give that volume for the number of hours you are going to use it. The heater blower motor in your car is designed to run on 12 volts. If the vendor you are looking at doesn't spec amp-hour capacity, look for an RC (reserve capacity) specification and multiply by 25, then divide by 60, and that will be close (but not exact) to the amp-hour capacity of the battery. 1000lbs pushing capacity. Edited by Ravenous, 17 November 2014 - 12:00 PM. the idea of hooking two identical 12V fans in series might be a useful alternative..bh. Can I run a 12V DC motor with a 20V DC? The risk is perhaps a few dollars of wasted expense if it fails. They can also be found on the big electronics distributor sites like Mouser or Digikey, but you are likely to have to pay a left nut for them. I think stopping and starting is the problem running continuously at  normal voltage is okay. The fuse is rated at a set number of amps, that is far less than the wires can handle, and it blows before the wires do. Solutions that allow aircraft crews to navigate in DVE are a critical need and a key area of interest for military and commercial applications. If you still can not find the information you will need to buy an amp meter and take readings on your equipment. What is the stall current of the motor? I have 110v power nearby, but do not want to run 110v to the water's edge for safety reasons. It soon learned that the system wouldn't work well on 12 and went to 18. Thoughts? This rating is amps per hour or amp/hr. This not to say you can't run into problems with higher voltages. You upsize the motors (more thermal mass for heat dissipation) for multiple starts/hour. There are two amp ratings on a battery. Operates 1 minute max then a few off. White Paper - Applying an Architecture-Driven Approach to Onboard Software Design, White Paper - Degraded Visual Environment (DVE) Meeting the Challenge, White Paper - Test Reuse Across MIL SIL HIL in a Development Workflow, eBook - How to Remove 5 Obstacles to Digital Transformation. if you do it work for short time each time and let the motor cool down for continuous operation use 12 V. 0. mikey77. I use car-plug type adapters for all my 12v equipment because they have fuses in them. For this reason I always keep a pack of spare fuses of various sizes for my equipment when travelling to a remote site. This makes it easy to measure the life in a battery by simply measuring its voltage. Example, mount uses 3 amps per hour, dew strips uses 4 amps per hour, camera uses 0.5 amps per hour and guide camera uses 0.5 amps per hour, this means you will need battery with a total of supply of 8 amps per hour. Only recommended if you know from the manufacturer it is supported at 18V! You might be able to power a 12V device with 18V, but not for as long. (or whatever in between). Whole thing is to operate a 1 inch bore RAM. I'm hoping to speed it up a bit. If a device needs 2 amps to run, and you have a 10 am-hour battery, you can run the device for 5 hours before you've emptied the battery. To start viewing messages, select the forum that you want to visit from the selection below. Turns out those two have a skimpy stock of 24V - buyextras.com has quite a few and thermalfx.com has some. Not all trolling motors are electronic, but if in fact it is a pulse width modulated setup it will not run. For astronomy equipment the only thing that would put a 12V battery in danger is a short circuit. The standard voltage regulator is the LM7805 that delivers 5vDC or ta a similar 3.3 volt regulator. Most 24 volt motors run quite happily, but at lower powe on 12 volts. i would still just wire the relay 12 volts. 1000lbs pushing capacity. If I attached a 12v 10a PS and the motor was rated 12v 5a, what would happen? I was thinking this could be good for someone with a 24V PV battery bank or perhaps a 12V when they have an additional 12V battery they could put in series to get 24V for operating these tools. The guard is easy enough – just slip it over the metal protrusion and use your winged bolt to tighten it down. That's why hand controllers are designed with the regulators close to the LCDs.
