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