These aren't real numbers. I've just plugged in hypotheticals to check that the theory behind it is correct.

Thanks for the links! I really appreciate all your help. I've been doing my reading... Sophiecentaur, you're right I should probably make my questions a little more specific. Below is the kind of situation I'm trying to get my head around. I hope you can see what I've been trying to get at, and...

When you say the generator will only put out as much power as is demanded of it, that's surely only when the generator as a unit is fitted with sensors to detect when it's current output is insufficient or excessive to the demand? If the IC engine is being given varying power demands by the...

I'll start doing more reading... I am really confused (I'm sorry, this is probably basic stuff). I know that if you put load on a motor, it draws more amps from the power source... but what if the kW are already predetermined by the output of the generator? If the generator produces so many kW...

I will... just to clarify... if in the above scenario, the generator was a 120 volt rated unit and it was connected to a 120 volt rated motor... the amount of amperage flowing would be directly proportionate to the speed of the motor, right?

Oh... I was told that reduction gears were used in the motors to compensate for the fact that EVs made use of high voltage low amperage systems to avoid weight issues and 'bulking up' of insulation etc. Remembering my sources, I was probably informed wrongly!

I will. I know that some trains have an enormous diesel engine at one end with a generator that powers the electric wheels... I didn't think of that. I'll have a trawl. I know that EVs try to use as high voltage as possible and then utilise reduction gears in the 'in wheel motors' that power...

I won't go into too much detail, but it's looking into using batteries in a supporting role, rather than a vital 'power storage' role... if that makes sense! Heh I know :wink: 1,775 amps seemed a lot, just wanted to make sure it wasn't 1.775 amps! (And if there wasn't something embarrasingly...

Wait... have I just asked a really stupid question? Reading my post back I've just realized I've given enough information to answer my own question... If it's producing 57.1 horsepower, that's 42.6 kW (42,600 Watts). Watts = Amps x Volts, so 42,600 = Amps x 24 So the number of Amps...

I want to investigate the conversion of an IC engine's power to electrical energy at source without battery storage. It's a personal project / investigation into passanger car hybrid systems. I see what you mean about the generators. So, say for example, you had the engine running at 3000...

Hi, thanks :) The engine will produce a kW output which will be reflected in the electricity output of the generator... but since Watts = Volts x Amps, how can you tell how many amps and volts you're getting in relation to engine torque, rpm and hp? I want to find out the connection between...

Hi all, Having trawled the web for too long, I don't seem to be able to find any resources surrounding a question I've had regarding turning kinetic power into electric power. Take the situation where an internal combustion engine's flywheel is connected to an alternator. The idea is that...
