Yes you can if the battery potential is less than the emf induced by dc motor. You need to rotate the motor with some speed by any external mechanical force. The motor will then convert it into electrical force and then deliver it to battery.
Can a DC motor be used to charge a battery?
A lead-acid battery is a source of direct-current (DC) electricity. When the battery begins to lose its charge, it must be recharged with another DC source. … An electric motor can be used in conjunction with a source of mechanical energy and a rectifier to recharge a 12V battery.
Can DC Motor create electricity?
Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive.
Does motor charge the battery?
The answer is ‘YES’, yes the car battery does charge while the engine is idling. … As long as the mechanical action of the alternator is taking place; that is, being turned by the engine crankshaft. Then the alternator is producing AC current, thereby charging the battery while your car is idling.
Can a 24v motor charge a 12v battery?
If you run a 12v motor from 24v its current drain and speed will still depend on the mechanical loading. However under no load it will now run at twice the speed at which it originally ran with 12v. Heating in the motor is still related to the current – so you can still run it at its full rated mechanical load/current.
How can I charge my motor battery?
Hooking up the Battery Charger
- Make sure the charger is off.
- Hook-up the positive cable on the charger to the positive terminal on the battery.
- Hook up the negative cable on the charger to the negative terminal on the battery.
- Set the charger to the slowest charge rate.
- Turn on the charger and set the timer.
Can you run an alternator with an electric motor?
Both the motor and the alternator have other losses too, such as windage and friction. You could connect an electric motor to an alternator, but the energy delivered by the alternator would be less the motor requires to turn it.
Can a motor be used as a generator?
Always use caution when working with electricity. Your permanent magnet electric motor can be used as a generator. All that needs to be done is to apply an external power source to spin the shaft of any permanent magnet electric motor and your motor becomes a generator.
Can DC motor run on AC supply?
We already know that in a DC Series motor the field winding has very less resistance than a DC Shunt Motor as the field is connected in series with the Armature Winding. So if we give AC supply on a DC Series Motor it will run perfectly. In fact, DC Series can run on both AC and DC supply.
How much electricity can a 12v DC motor generate?
12v DC motor with maximum 1.5A capacity can generate 18W of power. 12v DC motor with maximum 3A capacity can generate 36W of power.
Does the alternator charge the battery?
The alternator supplies all of them with direct current (DC) power. Your alternator is also responsible for charging your car battery while driving. The alternator works by turning mechanical energy into electrical energy.
Does a car battery charge while off?
Battery Life (and Death)
Of course, a battery can maintain a charge while the engine is on, but once it’s off, electronics draw directly from the battery. To avoid this recurring auto nightmare, always turn the headlights and interior lights off when you’re done driving.
How long does it take to charge a car battery with a 12 volt charger?
Car batteries usually hold 48 amps, so it will take about 12 hours to reach a full charge using a 12 volt charger. It takes around 30 minutes for an electric vehicle to charge to 80%.
What happens if you charge a 24 volt battery with a 12 volt charger?
If you just plug a 12 volt a battery into a 24 volt charger it will die in a matter of hours.
Can I charge a 24 volt battery with a 12 volt charger?
You cannot use the 12V charger directly to charge a 24V battery. To do the task you will need a boost converter capable of generating output voltage greater than 24V. Boost converters step up the voltage, keeping the input and output power constant.
Can you run a 24 volt DC motor on 12 volts?
24v hooked to 12v will spin for a while on a full battery but there will be no torque. You could stop it with your hand. It is like running your motor with half the spark plugs missing.
