Converting Solar Energy into Electrical Energy

[thekiso2009]

I am currently working on a project that requires me to design and analyse a solar powered. My motor has features such; 36v (Max), 300A (Max), 93% efficiency, 2.5mΩ, 12kW (Max).

I used the maximum power and the efficiency to calculate the power input (from the battery). How do i calculate the amount of current that will be drawn by motor from the battery?

I am a Mechanical Engineering student
Thanx

Sounds like a homework problem. Did you take Physics 101 yet? The current is easily over 50x the current drawn by the starter in my car with a 12-volt battery.

for asking!

I can offer some insight into your project and the calculation you are trying to make. In order to calculate the amount of current that will be drawn by the motor from the battery, you will need to use the formula P=IV, where P is power, I is current, and V is voltage. Since you have already calculated the power input from the battery, you can rearrange the formula to solve for current (I=P/V). Using the values of 36V and 12kW, you can calculate that the current drawn by the motor from the battery will be approximately 333.33A. It is important to keep in mind that this is the maximum current that the motor can draw, and it may vary depending on the load and other factors. Additionally, you may also want to consider the effects of the motor's internal resistance (2.5mΩ) on the current drawn from the battery. Overall, it seems like you have a well-designed and efficient solar powered motor, and I wish you success in your project!
