Cut this out, clipping the wires as close to the board as possible and throw out the board. For an ideal permanent-magnet DC motor the voltage controls the speed and the torque controls the current. And by accident the output frequency was 4.3kHz. am i able to use the 6v battery to run the motor?, i assume this will drain the battery fast, but its rechargeble. You can get batteries for the space you are looking for at either 6v or 12v. it will do well, but 50% of the voltage is a lot to lose. Hello, I have 2 old cars with 6V systems that I converted everything to 12V except for the starter. For really low supply voltages the stall torque will be less then the normal working torque at the nominal voltage. Plan to replace this switch with a transistor. Why is this? The working torque will probably be the same as this is limited by the current in the windings and the thermal considerations. if it works, it works. You can do this by combining each pair of 6V batteries and then wiring them together in parallel like you would 2 12V batteries. the motor will also have less power. For a 12v negative system, the ignition switch wire goes to … If the 9V adapter can handle this then you risk burning out the motor. It is easy to adjust with a potentiometer. If you’ve got an electrical device that operates on 6 volts, connecting it to a 12-volt battery will break it. What does this mean, well when you apply the 6V the motor must have sufficient torque to start rotating. 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. 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? See. This 2 channel 6v relay board is under the unit in a panel accessible by 4 screws. 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. 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. It'll just run slower. If you have 6 or 12V available it hurts nothing to run your relays off your motor supply. Wiki User Answered . At 9V it leaves only (9/12)^2=0.56 times the power at 12V. 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. I would like to drop the operating starter volt to about 9V. Not only that, you can power an arduino with 6-12v so a 6v power supply could drive both. If you apply 6V to a 12V incandescant lamp you will get about 1/4 output. I mounted my 12v battery under the front axle with some wood and zip ties. 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. Most 12v relays need about 12v to “pull-in” but will “hold” on about 6v. You cannot use 7806. I also build a op amp (LM358) based PWM for test purpose. try it. 18 April, 2017 . by cutting the voltage in half you have effectively doubled the current. The material (copper wire) in the 6V is very heavy compared to that of a 12V. 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. http://www.ecircuitcenter.com/Circuits/dc_motor_mo... http://lancet.mit.edu/motors/motors3.html. Put an ammeter in series with the blower motor and run it on both 6 and 12 volts and note the numbers. 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. In general terms, a 6V toy doesn’t have as much power as a 12V toy. 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. There is a resistor in the switch that lowers the voltage. If motor performance is your factor, then the voltage makes a huge difference. If you want current 1.3A output. The heater blower motor in your car is designed to run on 12 volts. As you can see on the bottom of the green circuit board the wire melted and acted like a fuse. You can adjust voltage from 5V to 12V with VR1. First I thought to use a … Assuming the motor takes eg. Hi, today I test if 12V DC motor can survive the 24V DC. While ride-on toys are great fun, they aren't very fast, and this can make them quite boring. It has a remote control feature and I don't want to risk simply adding a 12v battery to it. Given that you're running them on 6v, this will be 6v - 2v. Depends on the load. When you run 12v on a 6v starter the voltage drops down to about 8v. The same thing will happen with a 24 volt motor with 12 volts applied. 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. 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. I am concerned that its life will be short. ], Formal verification of safety-critical software, software development, and electronic design and prototyping. Join Yahoo Answers and get 100 points today. Not all trolling motors are electronic, but if in fact it is a pulse width modulated setup it will not run. 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. 12V to 6V DC converter using LM317. if the motor will turn and does not become super heated, it will work just fine. stop speculating. [EDIT: I am assuming a permanent-magnet motor. If you are 6v negative ground going to 12v negative, you can leave the wiring to the coil alone. Some need 6V constant voltage. To converter classic high and low output stators to 12 volts follow these simple steps: What happens when you lower the speed of a 12 volt motor, whether it's a wiper motor or fan motor? That's all! Look at the circuit below. 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. 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. 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. How come when I connect two 9V batteries to a breadboard, each with an individual connector, the total voltage doesn't increase? If the motor can't start turning because it does not have sufficient torque, you do risk burning out the motor. 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. so cutting V in half in your case, really means that you get only 25% of the power. 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. You can sign in to vote the answer. [EDIT: I am assuming a permanent-magnet motor.] speed and torque have an inverse relationship. Compare this to the '3-12V' RS-380PH-4045 which has 45 turns of 0.4mm wire. out of curiosity? I can't get more than 2 LED's to light up on my arduino in a in-series circuit. Whether you run it off the Arduino's supply or the motor supply is moot, since you need a transistor anyway. the speed of a dc motor is usually voltage dependent. Re: Can you run a 24V motor on 12V battery? 2A at 12V. If i do supply a 12v motor with 6V batteries, does it lower the torque of the motor?, if so how much? I can… the slower the motor is able to operate, the more torque it has. So you have reserve power to … hoping I can do this, maybe the motor will run faster (20% faster with 7.2, 60% faster with the 9.6, right? ) 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. This new 12-volt supply has enough power to run a modern 12V regulator rectifier. It's a well known fact the the power required to just start a motion is higher that what is required to sustain it. 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. What's the difference between using 10 watts (5 Volts, 2 amps) and 10 watts (2 Volts, 5 amps) to power something. Once that happens it will run to it's maximum speed, depending on the load. In broad terms - imagine modifying your feeder circuit to include a manual switch which, when pushed, triggers whatever your action is. Thanks in advanced :)? If the motor is rated for 12V, it's what it's optimized for. The thing is about simple DC motors, is that they have a torque versus speed characteristic curve. 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 answer should be obvious when you consider that motors have multi-speed switches. [ I DO NOT respond to personal messages, I WILL delete them unread, use the forum please ]. so i've read on my dc motor's datasheet that it can take 6v-18v, but recommended 12v. And yes, the motor survive 15 minute run without overheating too much. Motor speed is inversely proportional to the number of turns, so your motor is probably rated for less than 6V. But you can use LM317. How to Upgrade the Ride on Toys From 6V to 12V. Joined: Sep 1, 2010 Oddometer: 49,064 Location: Georgia. This will increase the speed and power of the wheels and raise the stress on the motor. When an input above 1.5v is applied to the input of the circuit, both transistors are turnedRead More Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. So the motor is made to run at all those voltages, maybe slow is 4 volts, medium is 8 and fast is 12. 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 … 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. You can try using a potentiometer that is variable resistance and gradually increase the resistance until you get the speed you want. By combining the high and low 6V supplies, you can create a 12V supply. 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. The faster the motor the less power it has. 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? this can cause complete failure if the motor overheats. Other than that the starter will likely last a long time if it is in good shape now. 2014-06-09 10:22:30 2014-06-09 10:22:30. 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 … Don't put 12v to a 6v system and expect it to work for very long. Let's take a step back for a moment and find out what type and model trolling motor this is. as long as this motor is not under high loads for long times it should work without fault. So if you run it on 6 volts it just goes slower that at 12. If I am understanding correctly you want to run two 6 volt batteries in series to get your 12V output. Thanks, Rod Oct 13, 2006 #2. mkaras Guest. What should I do? The motor can either provide you maximum torque (how strong it is) or maximum speed (how fast it can go). this means that if it is meant to run at more than one speed, it should work pretty well at 6v. Look at the circuit below. You can run it on less voltage, the problem is that you have to have sufficient power to overcome the rotation inertia. 2) increased current- to attempt to maintain the rated hp the motor will increase its current draw. there is a reason it was designed to run on 12v. For example, if your child wanted to go up a steep drive, a 12V and even a 24V … There is a resistor in the switch that lowers the voltage. 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). The 220u charges via the 2k2 and bottom diode. How do you think about the answers? When a lower speed is selected, a resistor is placed in series with the motor, thus reducing its voltage. Top Answer. So like someone else said, you might not get away with 6V. Description This circuit allows a 12v relay to operate on a 6v or 9v supply. Can a 12v dc motor run with a 6v battery? You can connect two six volt batteries to a 12 volt circuit. It will slow the motor down,and could cause the motor to stop working. #4. troidus, Feb 12, 2014 #5. troidus Long timer. Still have questions? Written by Michelle Course . 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. buddy said: I have a 6 volt cordless tool. Negative to positive, positive to negative. Can I run it with a 7.2 or 9.6 volt battery pack? 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. Finally, use R = voltage (which is 4v) / current (which you … What happens when you lower the speed of a 12 volt motor, whether it's a wiper motor or fan motor? everyone is making this far to complicated. It is the original 6V but I run it with 12V. I would say it won't work with 6V. Step by Step Stator Conversion Guide. but that's okay. Instead of using 6v to slow down the motor use a reducing gear or reducing pullys. nothing else is known about this motor. WIll it hurt the motor … At 9V it will try to spin 50% faster and draw about twice as much power. 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. Get your answers by asking now. It sounds complicated but it's really quite simple. May 13, 2012, 11:24 am Last Edit: May 15, 2012, 09:54 am by dc42 Reason: 1. It can give current more up to 1.5A. Depends on the motor, but most will work fine, albeit with a lot less power. 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. Using gears you can turn the load at a slower speed. To solve this problem you may need to convert 6v to a 12v power wheels. 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. why can you get the correct motor for the voltage or visa-versa.
