You can write a program for it by using PW modulation or just apply three-phase to a three-phase generator, like a car generator to be driven by another car generator with no diodes.

Have them in delta mode and make sure you excite both rotors through a current limiter at the same time (max 2Amp).

Better still if the electrically driven generator has a variable current limiter connected to its rotor so you can adjust the current to observe the torque controllability of it while the other generator's running at constant speed.

To vary the speed of it vary the generator's frequency by varying its speed.

This is what effectively the hybrid cars use as their generator-motor.

Read this!

Let us know how you go!

thnk u..i would like to know the simulink for using a VFD for 3 phase induction motor with pump as the load..How can i show that by using a VFD it is more efficient in matab simulink?
