If you’ve got an electrical device that operates on 6 volts, connecting it to a 12-volt battery will break it. If I am understanding correctly you want to run two 6 volt batteries in series to get your 12V output. 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. First I thought to use a … hoping I can do this, maybe the motor will run faster (20% faster with 7.2, 60% faster with the 9.6, right? ) I would like to drop the operating starter volt to about 9V. If you are 6v positive ground going to 12v negative, you need to switch the two wires on the coil. 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. So the motor is made to run at all those voltages, maybe slow is 4 volts, medium is 8 and fast is 12. To converter classic high and low output stators to 12 volts follow these simple steps: 2014-06-09 10:22:30 2014-06-09 10:22:30. Some need 6V constant voltage. When an input above 1.5v is applied to the input of the circuit, both transistors are turnedRead More The same thing will happen with a 24 volt motor with 12 volts applied. You can connect two six volt batteries to a 12 volt circuit. [ I DO NOT respond to personal messages, I WILL delete them unread, use the forum please ]. the motor will also have less 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. The working torque will probably be the same as this is limited by the current in the windings and the thermal considerations. You cannot use 7806. 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. Can a 12v dc motor run with a 6v battery? if it works, it works. 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. 18 April, 2017 . 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. Can I run it with a 7.2 or 9.6 volt battery pack? So like someone else said, you might not get away with 6V. Compare this to the '3-12V' RS-380PH-4045 which has 45 turns of 0.4mm wire. Negative to positive, positive to negative. So if you run it on 6 volts it just goes slower that at 12. If you have 6 or 12V available it hurts nothing to run your relays off your motor supply. Instead of using 6v to slow down the motor use a reducing gear or reducing pullys. Whether you run it off the Arduino's supply or the motor supply is moot, since you need a transistor anyway. This 2 channel 6v relay board is under the unit in a panel accessible by 4 screws. Not only that, you can power an arduino with 6-12v so a 6v power supply could drive both. by cutting the voltage in half you have effectively doubled the current. But you can use LM317. I'd be worried about the smaller lens being less visible. You can get batteries for the space you are looking for at either 6v or 12v. How do you think about the answers? You can run it on less voltage, the problem is that you have to have sufficient power to overcome the rotation inertia. it will do well, but 50% of the voltage is a lot to lose. nothing else is known about this motor. It can give current more up to 1.5A. The motor can either provide you maximum torque (how strong it is) or maximum speed (how fast it can go). At 9V it will try to spin 50% faster and draw about twice as much power. In general terms, a 6V toy doesn’t have as much power as a 12V toy. What does this mean, well when you apply the 6V the motor must have sufficient torque to start rotating. There is a resistor in the switch that lowers the voltage. this can cause complete failure if the motor overheats. Once that happens it will run to it's maximum speed, depending on the load. buddy said: I have a 6 volt cordless tool. If the 9V adapter can handle this then you risk burning out 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? It will slow the motor down,and could cause the motor to stop working. Look at the circuit below. Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. 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. Depends on the motor, but most will work fine, albeit with a lot less power. Let's take a step back for a moment and find out what type and model trolling motor this is. If i do supply a 12v motor with 6V batteries, does it lower the torque of the motor?, if so how much? The faster the motor the less power it has. Cut this out, clipping the wires as close to the board as possible and throw out the board. While ride-on toys are great fun, they aren't very fast, and this can make them quite boring. 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. if the motor will turn and does not become super heated, it will work just fine. You can do this by combining each pair of 6V batteries and then wiring them together in parallel like you would 2 12V batteries. If the motor can't start turning because it does not have sufficient torque, you do risk burning out the motor. so cutting V in half in your case, really means that you get only 25% of the power. there is a reason it was designed to run on 12v. 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. To solve this problem you may need to convert 6v to a 12v power wheels. I am concerned that its life will be short. but that's okay. I also build a op amp (LM358) based PWM for test purpose. And yes, the motor survive 15 minute run without overheating too much.
