Output Max Amps

[erwin1991c]

What output current will I get if I have an input voltage of 700 volts at 1 amps and if I step the voltage down to 230 volts what would be the max amps I'll get.

you can't get any more power out of it than you put in, minus your losses.

Erin to start with what are you wanting to put 700 volts in what to get 1amp I guess there’s not enough information

A step down transformer

Erin to start with what are you wanting to put 700 volts in what to get 1amp

input 700 volts, 1 amp, 700 watts
output 230 volts, 3 amps, 700 watts

Is it a 3 phase transformer and what’s the KVA rating of the transformer

 

[erwin1991c]

Didn't think about that yet. 700 volts at 1 amp is single phase using a generator. I want single phase 230 volts. I want to know what max amps I'll get if I want to step down to 230 volts. Please advise

What is your normal voltage

So if you start your generator you get 700 volts

So if you start your generator you get 700 volts

If you want to step down to 230 volts you will need a transformer

I’m curious where did you get a generator that puts out 700 volts

 

[erwin1991c]

I'll be connecting 100 motors in series (model of motor is 775 motor). All I know is that the winding of the month can handle around 1 amp current. Assuming 1 amp and 700 volts if I want to use a transformer to step it down to 230 volts what would be the max amps I'll get.

Hi - if it was a perfect transformer with no losses its a simple calculation 700/235 Amps. As this transformer doesn’t exist you’ll get a bit less.

 

[DPG]

Out of interest why are you connecting 100 motors in series?

Oops, where’d that extra 5V come from?

 

[marconi]

erwin991c - the idea of connecting 100 motors in series is not a good one and fraught with danger. Could you say more about what you want to achieve?

Series connection , may confuse voltages present in circuit ,
you can have a load present , but still exceed insulation capabilities else where !
