How long can a DC motor run on battery?
Thus, as long as your load is the same, theoretically, motor draws same current. NOTE: Of course current change when the Armature voltage changes, but this is negligible. 75A/h means “75A for one hour.” Maximum. So if your motor, on average, draws 1.5A, and ran continuously, then it should run for 75/1.5 = 50 hours.
How do I choose battery capacity?
To obtain the energy content of a battery, multiply the battery capacity in Ah by the voltage to obtain energy in Wh. For instance, a nickel-metal hydride battery with 1.2 V, and a lithium-ion battery with 3.2 V may have the same capacity, but the higher voltage of the lithium-ion would increase the energy.
How much power does a 1 hp motor consume?
There is a 1 HP motor here. 17904 Watt-hour is equal to 17904/1000 units and 1 HP for 24 hours is 746 24. When the 1 HP motor is running continuously for 24 hours, 17.904 units of Power will be consumed.
How much power does DC motor use?
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.
How many volts does a DC motor need?
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.
How many amps does it take to run a 1hp motor?
Most car batteries are 60–70 amp hour, so you could estimate that a car battery could run a 1hp motor for 1 hour. However, most motors run on ac current so you would need to install a heavy duty (750w+) transformer, which would decrease your efficiency.
What size battery do I need to run a 1 hp motor?
So at 1 HP you’re consuming 4 HP of electricity or about 3KW. If your battery is a 12V battery then you’ll need to deliver 250 A continuously. Add a safety factor (20\% is a good idea) to get 300A. So you need a battery that can deliver 300A for as long as you want to run the motor.
How many Watts Does It take to power 1 hp?
techncically 1 HP is 746 watts, by definition. But you did not mention type of battery or motor.I cannot tell what kind of load the motor is taking . If I just take a WAG and say the inefficiencies are 50\% you would need about 1.5 kw of battery power.
How long will a 75 amp battery run a 12V motor?
If the DC motor is 12 v and has 3 amps, then is 36watts and a 12 volt battery on 75 amps/h will give you 12*75=900watts/36 = 25 hours. I am interested in spinning a PMG and kick the wind out of equation. The torque demanded would shrink some of that 25 hours. I suggest Varta Silver or gel kind of batteries. Succes ! It’s not 75 A/h, it’s 75 Ah.
