How many volts does it take to power a DC motor?
Typical DC motors may operate on as few as 1.5 Volts or up to 100 Volts or more. Roboticists often use motors that operate on 6, 12, or 24 volts because most robots are battery powered, and batteries are typically available with these values. Operating Current.
Can DC motors generate electricity?
A DC motor can produce a fair amount of electricity by manually rotating the shaft. This would then turn the function of the motor to a generator. Attach some sort of prime mover (an independent source of energy to turn the generator like a wind turbine, a gasoline or diesel engine etc.)
Can a small DC motor produce electricity?
Yes. Practically any type of motor can also serve as a generator. A DC motor operated in reverse supplies current from the positive terminal. A synchronous motor (including permanent magnet (PM)) will produce power if run by an engine.
Can you run a 12 volt motor on a 12-volt alternator?
Sure you can run a 12 volt DC motor connected to a 12 volt DC alternator to charge a battery, but why would you want to go through all that trouble when you could just charge the battery with the 12-volt source you are running the motor with.
Can You charge a 12V battery with a generator?
Only and only if the motor runs off a separate power supply to turn the generator and then the generator should be able to provide a voltage higher than the 12V battery which it has to charge. The rating of the generator also has to be sufficient in order to supply the battery on charge with enough current.
What determines the state of charge of a 12 volt battery?
State of charge 12 volt Standard Batteries Battery state of charge is determined by reading either terminal voltage or the specific gravity of the electrolyte. The density or specific gravity of the sulphuric acid electrolyte of a lead-acid battery varies with the state of charge (see table below).
How does battery voltage react to charging and discharging?
Battery voltage reacts highly to charging and discharging. As a battery is charged the indicated voltage increases and, as discharging occurs, the indicated voltage decreases. With experience, one can accurately determine state of charge using a voltmeter.
