The 220u charges via the 2k2 and bottom diode. If you’ve got an electrical device that operates on 6 volts, connecting it to a 12-volt battery will break it. First I thought to use a … am i able to use the 6v battery to run the motor?, i assume this will drain the battery fast, but its rechargeble. Don't put 12v to a 6v system and expect it to work for very long. When an input above 1.5v is applied to the input of the circuit, both transistors are turnedRead More But you can use LM317. I am in Engineering school and I will get a Msc when I graduate.Its near my house.I won a scholarship for a Business College which is at the? Using gears you can turn the load at a slower speed. Step by Step Stator Conversion Guide. Wiki User Answered . This new 12-volt supply has enough power to run a modern 12V regulator rectifier. You can make the 6V DC motor run for just a short while before it cuts off by itself after a while as it will try to protect it from damage due to overvoltage as the supply exceeds the operating voltage input range which is typically 3V - 6V. To get the best performance from a direct current (DC) motor it is advised to use the same voltage power supply as the input voltage of the motor. And yes, the motor survive 15 minute run without overheating too much. You can run it on less voltage, the problem is that you have to have sufficient power to overcome the rotation inertia. You can get batteries for the space you are looking for at either 6v or 12v. You cannot use 7806. Note that you'll have to have the motor shaft connected to whatever load you're running in order to properly judge the effect of the reduced voltage; many motors seem to run almost as fast on half the voltage as they do on their full voltage if you only judge the speed of the unloaded shaft. I can… 2014-06-09 10:22:30 2014-06-09 10:22:30. Instead of using 6v to slow down the motor use a reducing gear or reducing pullys. Finally, use R = voltage (which is 4v) / current (which you … if the motor will turn and does not become super heated, it will work just fine. [EDIT: I am assuming a permanent-magnet motor. The thing is about simple DC motors, is that they have a torque versus speed characteristic curve. The motor can either provide you maximum torque (how strong it is) or maximum speed (how fast it can go). So if you run it on 6 volts it just goes slower that at 12. Congress is looking to change key 401(k) provision, Why 'Crocodile Dundee' star, 81, came out of retirement, 21-year-old arrested in Nashville nurse slaying: Police, Tense postgame handshake between college coaches, College students outraged as schools cancel spring break, COVID-19 survivors suffering phantom foul smells, 5 key genes found to be linked to severe COVID-19, FKA twigs sues LaBeouf over 'relentless abuse', Odd couple introduces new push for stimulus checks, Biden urged to bypass Congress, help students, 'Friday' actor died after experiencing COVID symptoms. While ride-on toys are great fun, they aren't very fast, and this can make them quite boring. Joined: Sep 1, 2010 Oddometer: 49,064 Location: Georgia. My idea is to use the 6v power supply that goes to the motor to instead trigger a relay to allow the 12v battery to run the motor (leaving all factory controls on 6v). [ I DO NOT respond to personal messages, I WILL delete them unread, use the forum please ]. speed and torque have an inverse relationship. For really low supply voltages the stall torque will be less then the normal working torque at the nominal voltage. it will do well, but 50% of the voltage is a lot to lose. why can you get the correct motor for the voltage or visa-versa. Unless the motor is very large, 6v motors tend to stall out very easily but it's a nice voltage to run everything at without a hassle. Answer. Thanks, Rod Oct 13, 2006 #2. mkaras Guest. #4. troidus, Feb 12, 2014 #5. troidus Long timer. http://www.ecircuitcenter.com/Circuits/dc_motor_mo... http://lancet.mit.edu/motors/motors3.html. That's all! 12V to 6V DC converter using LM317. If the 9V adapter can handle this then you risk burning out the motor. I mounted my 12v battery under the front axle with some wood and zip ties. If you want to slow it down, then use up the 12V battery until it's like 11V in order to make your motor slower or use a resistance in series so the voltage that reaches the motor will be slightly lower than 12V. If in fact this is a 12/24 volt 4spd or 5spd it will not make a difference. 2) increased current- to attempt to maintain the rated hp the motor will increase its current draw. Look at the circuit below. The heater blower motor in your car is designed to run on 12 volts. There is a resistor in the switch that lowers the voltage. Given that you're running them on 6v, this will be 6v - 2v. It has a remote control feature and I don't want to risk simply adding a 12v battery to it. try it. So like someone else said, you might not get away with 6V. Depends on the load. Description This circuit allows a 12v relay to operate on a 6v or 9v supply. Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. This will increase the speed and power of the wheels and raise the stress on the motor. I can't get more than 2 LED's to light up on my arduino in a in-series circuit. Put an ammeter in series with the blower motor and run it on both 6 and 12 volts and note the numbers. the slower the motor is able to operate, the more torque it has. The answer should be obvious when you consider that motors have multi-speed switches. The faster the motor the less power it has. Let's take a step back for a moment and find out what type and model trolling motor this is. this means that if it is meant to run at more than one speed, it should work pretty well at 6v. How come when I connect two 9V batteries to a breadboard, each with an individual connector, the total voltage doesn't increase? there are only two things that you need to consider: 1) loss of power- if the motor is rated at 1/64hp it will try to maintain that at any voltage. out of curiosity? Written by Michelle Course . There is a resistor in the switch that lowers the voltage. buddy said: I have a 6 volt cordless tool. How to Upgrade the Ride on Toys From 6V to 12V. Negative to positive, positive to negative. There is a complex explanation for why you could burn your motor if it does not rotate (no back emf... = max current) but I can spare you.... Keep it mind that by ohms law, power is P=V^2 / R. You can consider that R is constant for the motor. The material (copper wire) in the 6V is very heavy compared to that of a 12V. For a 12v negative system, the ignition switch wire goes to … nothing else is known about this motor. So you have reserve power to … In broad terms - imagine modifying your feeder circuit to include a manual switch which, when pushed, triggers whatever your action is. ], Formal verification of safety-critical software, software development, and electronic design and prototyping. If the motor is rated for 12V, it's what it's optimized for. When you run 12v on a 6v starter the voltage drops down to about 8v. Cut this out, clipping the wires as close to the board as possible and throw out the board. By combining the high and low 6V supplies, you can create a 12V supply. If i do supply a 12v motor with 6V batteries, does it lower the torque of the motor?, if so how much? there is a reason it was designed to run on 12v. the speed of a dc motor is usually voltage dependent. Hi, today I test if 12V DC motor can survive the 24V DC. 2A at 12V. Not to mention, the stock foot switch is only rated for 10A, which can be welded open during failure, resulting in a dangerous runaway situation. Whether you run it off the Arduino's supply or the motor supply is moot, since you need a transistor anyway. Motor speed is inversely proportional to the number of turns, so your motor is probably rated for less than 6V. When a lower speed is selected, a resistor is placed in series with the motor, thus reducing its voltage. If you have 6 or 12V available it hurts nothing to run your relays off your motor supply. if it works, it works. [EDIT: I am assuming a permanent-magnet motor.] Can a 12v dc motor run with a 6v battery? It's a well known fact the the power required to just start a motion is higher that what is required to sustain it. If you apply 6V to a 12V incandescant lamp you will get about 1/4 output. How do you think about the answers? However, if you have a 24 volt DC motor, but only have a 12 volt power supply, such as a car battery, your motor will still operate, although the speed at which it rotates will be slower. But if you run that 6 volt motor at 12 VDC, then the PWM required to develop the same power would be 1/2 that when operating at 6 VDC. The same thing will happen with a 24 volt motor with 12 volts applied. And by accident the output frequency was 4.3kHz. At 9V it leaves only (9/12)^2=0.56 times the power at 12V. Asked by Wiki User. In general terms, a 6V toy doesn’t have as much power as a 12V toy. Likewise, 24V ride on’s are significantly faster than the 12V ride on’s and last longer while 36V ride on’s improves on the speed and battery life of … This will work well and allow you to also run a 12V battery with those two 6V batteries, when you then connect the output power 12V of the two 6V batteries in parallel with your 12V battery. everyone is making this far to complicated. Re: Can you run a 24V motor on 12V battery? Depends on the motor, but most will work fine, albeit with a lot less power. A motor designed to work on 6V can work safely only at 6 V +25% (max) ie approx 7.5 volt.. that will change the rmp.. more over the current capacity of the … as long as this motor is not under high loads for long times it should work without fault. Once you’ve wired 2 6V batteries in series to make a 12V battery it’s really easy to wire 2 more 6V batteries together in series/parallel to increase the amp hours. WIll it hurt the motor … The stock 6v harness is undersized and you will run the risk of melting wires/starting fires if you try to run 12v/30A through tiny wires. Like Tim said, it will spin much faster and will heat up quicker so you can't stay on the starter very long and you need to wait long for cool down. Some need 6V constant voltage. If what you've done is bright enough then go with it. Get your answers by asking now. So the motor is made to run at all those voltages, maybe slow is 4 volts, medium is 8 and fast is 12. It'll just run slower. i bought a pocket knife on Amazon but I can't get the package open because I don't have a pocket knife. It is easy to adjust with a potentiometer. If I am understanding correctly you want to run two 6 volt batteries in series to get your 12V output. The thing to remember is doubling voltage doesn't double the amps; amps may go up, but as long as you don't get more than about 10% more, it should be OK. More amps means more heat, and heat is what'll kill the motor. That means that the equivalent DC resistance of the (running) motor is 12/2=6 Ohm If you apply 9V over 6 Ohm, the current will be just 9/6=1.5A So, current is reduced, but worse, power is reduced by the square. When running that 6 VDC motor at 6 VDC, 100% is exactly that - 100% output power. 1 2. If the motor can't start turning because it does not have sufficient torque, you do risk burning out the motor. If the device has its own internal switching regulator, the voltage probably won’t be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may draw too much power and the power supply will be damaged. I'd be worried about the smaller lens being less visible. Can I run it with a 7.2 or 9.6 volt battery pack? Not only that, you can power an arduino with 6-12v so a 6v power supply could drive both. As you can see on the bottom of the green circuit board the wire melted and acted like a fuse. However, by inserting another 6-volt device, such as a 6-volt light bulb, in series with your other 6-volt device, you can easily switch your 12-volt battery to 6 volts. If you run the motor on 6v then its no-load speed will be about half what it would be at 12v, and its stall torque will be about half what it would be at 12v. so i've read on my dc motor's datasheet that it can take 6v-18v, but recommended 12v. You can try using a potentiometer that is variable resistance and gradually increase the resistance until you get the speed you want. The working torque will probably be the same as this is limited by the current in the windings and the thermal considerations. If you are 6v negative ground going to 12v negative, you can leave the wiring to the coil alone. Not all trolling motors are electronic, but if in fact it is a pulse width modulated setup it will not run. For an ideal permanent-magnet DC motor the voltage controls the speed and the torque controls the current. To converter classic high and low output stators to 12 volts follow these simple steps: Thanks in advanced :)? You can connect two six volt batteries to a 12 volt circuit. I have a 12 v electric motor I want to run on 6v to slow it down will this work or just bugger the motor up? Plan to replace this switch with a transistor. It is the original 6V but I run it with 12V. the motor will also have less power. Look at the circuit below. Top Answer. If you are 6v positive ground going to 12v negative, you need to switch the two wires on the coil. Assuming the motor takes eg. 18 April, 2017 . I would say it won't work with 6V. It will slow the motor down,and could cause the motor to stop working. Hello, I have 2 old cars with 6V systems that I converted everything to 12V except for the starter. You can sign in to vote the answer. What should I do? This 2 channel 6v relay board is under the unit in a panel accessible by 4 screws. Join Yahoo Answers and get 100 points today. I also build a op amp (LM358) based PWM for test purpose. What's the difference between using 10 watts (5 Volts, 2 amps) and 10 watts (2 Volts, 5 amps) to power something. You should have no problems as long as you don't crank the engines over for long periods of time or try moving the car in gear with the starter. hoping I can do this, maybe the motor will run faster (20% faster with 7.2, 60% faster with the 9.6, right? ) by cutting the voltage in half you have effectively doubled the current. It sounds complicated but it's really quite simple. At 9V it will try to spin 50% faster and draw about twice as much power. What determines the maximum speed or the maximum torque depends on the physical caracteristics of the motor (how many windings in the motor coils, mechanical resistance, etc..) and obviously voltage. I know of only a few relays that can be driven from a logic output and their contacts are too small to run your motors. For example, if your child wanted to go up a steep drive, a 12V and even a 24V … You can adjust voltage from 5V to 12V with VR1. Compare this to the '3-12V' RS-380PH-4045 which has 45 turns of 0.4mm wire. You can either do it yourself, or find a friend who can connect the two six volt battery wires to give the motor more power. What happens when you lower the speed of a 12 volt motor, whether it's a wiper motor or fan motor? I would like to drop the operating starter volt to about 9V. I am concerned that its life will be short. You can do this by combining each pair of 6V batteries and then wiring them together in parallel like you would 2 12V batteries. stop speculating. If you run the motor on 6v then its no-load speed will be about half what it would be at 12v, and its stall torque will be about half what it would be at 12v. See. It can give current more up to 1.5A. What happens when you lower the speed of a 12 volt motor, whether it's a wiper motor or fan motor? What does this mean, well when you apply the 6V the motor must have sufficient torque to start rotating. Real motors aren't ideal - as you increase the load the resistance of the windings causes IR losses and the voltage drop means the speed decreases from the ideal. If motor performance is your factor, then the voltage makes a huge difference. this can cause complete failure if the motor overheats. Still have questions? Once that happens it will run to it's maximum speed, depending on the load. If you want current 1.3A output. Most 12v relays need about 12v to “pull-in” but will “hold” on about 6v. May 13, 2012, 11:24 am Last Edit: May 15, 2012, 09:54 am by dc42 Reason: 1. The main difference between a 6V ride on and a 12V ride on would be the run time (battery life), the terrain it can be used on and the age recommendations. To solve this problem you may need to convert 6v to a 12v power wheels. so cutting V in half in your case, really means that you get only 25% of the power. but that's okay. Why is this? Other than that the starter will likely last a long time if it is in good shape now. Measure the current drawn when running the LED light on 12v - .this will stay the same when running on 6v The voltage across the resistor will be the the supply voltage minus the LED voltage.
