I am trying to design a toroidal transformer with multiple secondary coils. The core of the transformer is rated at 2500VA. Each of the secondaries powers a dc servo motor wich is subjected to a highly dynamic load.
There are 3 motors that require 24v at 3-30 amps depending on the load, and 2 motors that require 15 volts at 1-7 amps depending on the load.
If I were to make a secondary winding for each of the motors, how would I calculate the current in each winding?
I know the formula for an ideal transformer is: Vs/Vp=Ns/Np=IP/Is but if the 3 24v motors are simultaneously drawing huge currents, does that mean the other motors will have too much current or is "Is" in that formula just the maximum available current and the motor will draw what it needs?
