Hello The equation for power consumption of a three phase induction motor is given by the equation: P = sqrt(3)*V*I*(PF) Does this differ from the power that is delivered to the motor. For example, if a motor is running at 460 volts, 30 amps with a PF of 0.82, then the power...

The equation I'm finding around the internet is voltage drop Vd = (2*L*R*I)/1000, where L is the length of the wire, R is the resistance and I is the current moving through the wire. This is consistent with the logic above except it is twice as much. I'm assuming this is to account for a...

Ok, thanks. I was hoping that the charge controller was able to convert that lost 98 watts (which is voltage potential) into available current to the load. Why is this not possible?

Ok, I have a 48 Volt charger in which i set the float, bulk, and equalizing voltages. It is rated up to 150 amps. The input to the system is a solar panel. The solar panel is rated at 60 volts and outputs about 8 amps. So if 480 watts is put into the charge controller, can I expect 480 watts...

Hello, simple question here! When a voltage is regulated down or up in a circuit by, let's say a DC/DC converter, does the corresponding current increase or decrease respectively so that the system remains consistent with the laws of conservation of energy? In other words, I want to know...

Ok, thanks guys for clearing up my minor confusion on these topics, this will help moving forward in my designs

Ok, this all makes sense to me. So the power lost over a wire with a length x is P = (Vin - Vout)*I, where Vin is the input voltage at the beginning of the wire and Vout is the voltage at the end of the wire determined by resistance R of a wire of gauge y and length x. The current through the...

Hello, I'm working on a project at which a large amount of current is being passed through a low voltage system (48 Volts). In one part of the system, there are connectors rated at 12 Volts in which the 48 volt DC current is passed through. How much power loss might I be suffering here...

Jim, When I said resistive load I indeed meant load mechanical load is resistive (friction and mechanical work). A pumpjack is synonymous with a nodding donkey if you've heard of that. When you think of a land oil rig you should think of a pumpjack. Its the rotating device that pumps...

Hello, I'm trying to find out how much energy an induction motor pulls over a 24 hour period when connected to a resistive load. The only data I have are the specifcations of the motor, so I can estimate how much energy it will draw based on what capacity it might be running at. Really...
