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 a motor charge battery?
yes a battery can be charged by motor. this what happens in generators and regenerative braking. its not an big task if battery is giving supply to the motor as it draws it bcuz the voltage is less than the 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.
Can you connect a motor directly to a battery?
Yes, It is safe. You can connect your DC motor directly to your battery(if the voltages are same) . Your motor will work continuously ~100 hours in this battery.
Does an alternator charge a 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.
Can a car alternator charge two batteries?
You can run two batteries on the same alternator. … The alternator registers these two batteries as a single large battery and charges them the same. The batteries self-regulate the amount of current they take as they charge. This means that a single alternator is effective for multiple batteries.
How does a 12v charging system work?
When voltage drops below 13.5 volts, the regulator will apply current to the field and the alternator will start charging. When the voltage exceeds 14.5 volts, the regulator will stop supplying voltage to the field and the alternator will stop charging. This is how voltage output from the alternator is regulated.
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.
Will a 12V motor run on 9V?
The 9V batteries are weak because the other half of the story is how much current they can supply. … It’s possible to run a 12V motor on 9V, but it will run slower and with less Torque.
How can you tell if a DC motor is bad?
Measure the resistance between the motor terminals and compare it with a known good motor (or the datasheet). If the coils have melted, they will have shorted and you’ll see a lower resistance. Or they will have broken altogether, and you’ll read infinite resistance.
