does the rotational port S recognize the load flow?

3 views (last 30 days)
for a projct I need to connect an asynchronous motor with a synchronous generator, which will supplement an island grid.
I used the rotational port S so I could add the clutch and a flywheel later, but I don't get the right load flow, from the motor to the generator, although the ASM is set as motor and SG as generator?
can anyone help me understand how the rotational port works? I didn't find informations in the documentation.

You can understand the rotational port as a welding joint with a rigid rotating rod. The rod beeing the "light green wire" in the simulink model. In the context of a motor, the rotational port would be the motorshaft, that can be connected to something. So if you want to connect the generator shaft with the motor shaft you simply have to connect both ports (see model below). The "Mechanical Rotational Reference" is a rigid rod that is not able to rotate. Every "rod" that is connected directly has the same rotational position,velocity and acceleration (and torque and inertia).
Hope that made it a bit more clear, but feel free to ask, if you do not unterstand something.
The model above should be what you need (if I understand correctly). But I am not really familiar with the Machine-Bocks, so take it with a grain of salt.

I unfortunately can't help with this regard, since it is much more specific to the machines/blocks
