Three/Mono Phase Asynchronous Motor Simulator
When repairing stuff with a motor the first question is:
“Is it the motor or is it the board that failed?”
For a recent Inverter Air Conditioner board repair the following tool helped to answer that question.

Simulate the circuit
The circuit can act as Induction Motor aka asynchronous motor .
Inverter Air Conditioners which use AC motors take the 220V from the grid and turn them into about 150V three phase AC which drives the motor.
