An electric motor, though, is as an alternating-current (AC) source. For the electric motor to provide DC energy, its output has to pass through an electronic circuit called a rectifier. An electric motor can be used in conjunction with a source of mechanical energy and a rectifier to recharge a 12V battery.
Can you use a DC motor to charge a battery?
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 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
Can a DC generator charge a battery?
And like your car, the real magic of a DC generator lies in the fact that it can charge batteries directly, without the wasted energy and the added complexity of an AC to DC battery charger.
Do you charge a battery with AC or DC?
Chemical reaction for creating these chemical conditions goes in one direction, and using them makes the direction reverse. Naturally, charging process depends on direction of current. This direction has to be maintained, meaning battery must get DC current. However, most charging is done using AC supply mains.
Can you use a DC motor to generate electricity?
The DC motor is a ready made generator that will generate electricity. All that you have to do is turn the Axle of the generator using a mechanical outside source of energy .
Is DC motor a generator?
Both brushed and brushless DC motors can be operated as generators.
Can I run a 12v DC motor on 18v?
No. You are applying too much voltage to the motor. This will cause too much current to flow, and in turn, burn out the motor. If it is rated for 12 volts, it should get at the most 10% more or 13.2 volts.
How many amps does a 12 volt DC motor draw?
At this point it is drawing the maximum amount of current and applying maximum torque. A low voltage (e.g., 12 Volt or less) DC motor may draw from 100 mA to several amperes at stall, depending on its design.
Can I run a 12v motor on 24v?
If you were to run a 12v motor off a 24v battery the stall current could then be excessive if it weren’t limited by the controller. Therefore, provided you chose a controller suitable for the motor you use, you can usually run a motor 12v motor from a 24v battery with no effect except that full speed is doubled.
Can you charge a 12 volt battery with a generator?
If you’re looking for a plug & play option, you can simply plug a good quality smart charger into the AC outlet of the generator and connect the 12V charging cables to the positive and negative terminals of the battery.
How do you charge a 12 volt battery with a generator?
How to Charge a Deep Cycle Battery From a Generator
- Inspect your deep cycle battery.
- Fill the generator with gasoline.
- Attach the battery charger alligator clips to the battery terminals.
- Plug the battery charger into the generator’s 120 volt outlet.
What size generator do I need to charge a 12 volt battery?
I recommend a generator with a minimum of 3500 watts and 8 amp power to charge your 12-volt RV battery. Your battery will charge a bit faster if you get a more powerful generator, but you should be OK with 3500 watts.
Can you charge a 12V battery with a 12V power supply?
YES, you can use 12V DC power supply for charging car battery. After charging for 18 hours, check battery voltage. If it is 11.5V or more, start engine (car) with it and keep it charging for at least 30 min.
How do DC chargers work?
A DC to DC battery charger works with a 12V battery by isolating your main 12V battery system from the vehicle’s alternator. The DC to DC charger will then boost the charge of the main battery to maximize its charging capacity. This process will allow you to get your battery 100% charged after a day of driving.
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.
Can you generate electricity with a brushless motor?
They are used in a plethora of devices and situations, from electric cars and wind turbines to hobbyist experiments. A brushless motor can generate electricity.A brushless motor can be as effective as a brushed motor in generating power but will require more maintenance.
Are the losses of DC motor the same with DC generator?
Copper loss is the power lost as heat in the windings; it is caused by the flow of current through the coils of the DC armature or DC field. This loss varies directly with the square of the current in the armature or field and the resistance of the armature or field coils.
Copper Losses.
| Armature: | Ia2 Ra |

How do you know if a DC machine is a motor or generator?
you see a prime mover connected to shaft, eg turbine, another motor, it’s a generator. If you see a mechanical load connected to the shaft, eg a fan or a pump, it’s a motor.
What is the difference between a DC motor and a DC generator?
The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.
Which DC motor is best for generating electricity?
Brushless DC motors (BLDC) or permanent-magnet synchronous motors (PMSM) are pretty much the same thing and are the best to use as generators. They generate AC, so they require a rectifier on the output.
