I have two different AC motor drivers and I need to test them for energy efficiency in an analysis tool (I know only LtSpice).
But I don't know how to model an AC motor. Driver's circuitries are given. They are 3-phase AC motor drivers. Can you tell me how should I model an AC motor and how to do an efficiency analysis in LtSpice?
I don't hink you can, definitely not in ltspice. Efficiency is Pout/Pin, but it depends on motor working point (velocity, acceleration, losses) , which you have to define. If you have a switching driver, it's even more complex,since power wasted on the driver almost doesn't depend on the motor, just on the current.
