It’s possible to run a 12V motor on 9V, but it will run slower and with less Torque.
What will happen if we power a 12 V DC motor with a 9V battery?
Your motor will run fastly and then it may damage , because you can run 12v motor on 9v power but you can’t do the higher voltage input on lower VTG load , yes you can use series resistor to reduce 12 v VTG in near 9v , but also decrease current so you can check motor speed enough or not .
Can I use 9V battery for 12V?
You cannot supply 9 V or 18 V to 12 V motor if it has to work properly. 2 batteries in series make it 18 V, which cannot be used for 12 V motor, which can at most tolerate 14 V, with 10% variation. A 9V battery is too small to run a motor of any good capacity, except may be a toy motor.
Can I run a 12V device on 9V?
You can’t use a 12V adapter to power a 9V guitar pedal. A pedal that only handles 9V can be destroyed by using a 12V adapter. It’s possible for a power supply to ruin your pedal even if you get the voltage right.
How long does a 9V battery last DC motor?
If the battery is a very good one, you might get 10 minutes before the motor is destroyed. But really, it all depends on which battery and which motor. If the motor were to survive, it could be between 5 minutes and 2 hours.
What can a 12 volt battery power?
Your 12V battery system will power most of your basic systems like your lights and some appliances in your RV. You’ll charge this battery system while plugged into shore power and draw from it while traveling or boondocking.
Will a battery charger run a 12 volt motor?
If it weighs several kg, the motor will probably not run well on a 12V 2A simple charger. But it also depends on the load you are putting on the motor. In general, the startup current for a brushed DC motor can be up to 10x the rated full current draw.
What happens if I use a 9V adapter on a 12V device?
Plugging in an adapter with a lower voltage would not generally harm the unit. But if the polarity is reversed then it probably would cause damage and that may be what has happened. It may just have blown a fuse.
Can I use a 12V power supply on a 9V router?
However, the 9 Volt router cannot be run on the 12 Volt UPS. The 9 Volt router is meant to be run on 9 Volts and attempting to power it with the 12 Volt UPS will result in an overvoltage thus permanently damaging the router. No, it will not be possible to do that.
Will a 9V charger charge a 12V battery?
You cannot use a 9 volt charger as it will not be capable of providing enough voltage. A 12 volt battery (I’m using a lead-acid battery as an example) needs a charging voltage of about 13.5 volts to properly charge the battery. The standard charge level typically used in automobiles is 13.7 volts.
What uses 9V power supply?
A lot of things use those small 9V batteries. Smoke detectors, some transistor radios (not so much any more), lots of handheld test equipment, electronic toys, etc. More and more things that in the past typically used 9V batteries are being designed to run from one to four AA or AAA cells.
Can I use 5v adapter for 9V?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn.
Can I connect DC motor directly to battery?
Yes it is perfectly safe, the 1.5 A specification of the motor is what it will draw when connected to a 12v source (in your case the battery) while the 150Ah rating of the battery is the capacitance of the battery, in other words how long it will be able to supply sufficient power to a load (the motor in your case) See
How long will 9-volt battery last?
Li-ion batteries have a nominal voltage of 3.6V and 3.7V. Rechargeable nine-volt batteries usually come in two options: these are NiMH and Lithium. Lithium batteries double the NiMH capacity. NiMH’s 9V battery capacity last for about four hours with the rechargeable Lithium lasts for 7 to 7.5 hours.
How strong is a 12V battery?
A Few Basics
| State of Charge | Specific Gravity | Voltage |
|---|---|---|
| 12V | ||
| 100% | 1.265 | 12.7 |
| 75% | 1.225 | 12.4 |
| 50% | 1.190 | 12.2 |
Can you run a TV on a 12V battery?
Powering your home TV from the 12-volt lighter socket in your car, truck or RV is possible. Since the home TV uses AC (alternating current) power and the vehicle produces DC (direct current) power which is stored in the battery, a power inverter is required to produce the type of power used by your television.
How long will a 12V 12ah battery last?
approximately 120 hours
The watts/volts are equal to the amps per hour. A tiny device such as led lighting of power 1.2 watts running on a 12volt power source will use 1.2W/12V = 0.1 amps. Therefore, a 12ah (amp-hour) battery will last for approximately 120 hours.
Can a 12v DC motor run on 5V?
Probably not. The motor will not have much torque, if any. Depending on the motor size the current draw will go up and is likely to be more than the charger can supply. 5Vdc is less than 1/2 the expected drive voltage of 12Vdc.
Can a mobile battery run a DC motor?
1 Answer. It is very unlikely that a cellphone battery can power a motor shield, assuming motors will be actually operated off it. Motors typically draw large currents, and while modern Lithium-Ion batteries have fairly high current rating, they are designed to supply just enough for a small portable device.
Can DC motor run on mobile charger?
Introduction: Emergency Mobile Charger Using DC Motor
The charger works on the principal of DC motor being used as a generator converting mechanical energy to electrical energy. But since the voltage required by a phone is 5V a voltage regulator IC 7805 is used to get the desired output voltage from the DC motor.
Can I use a 9V power supply on a 12V keyboard?
It shouldn’t be. But your power supply may overheat and burn out.
