Phase Voltage not changing with field voltage in a synchronous motor setup.
1 visualización (últimos 30 días)
I'm trying to build a circuit for use in simulating a synchronous motor. I've got some initial setup, and when I first run the simulation I get some variance in my values. However, after I run it a few times, the phase voltages don't change very far from 120VAC. Even if the field voltage is dropped to 50V. Can someone elaborate on what I may be missing? I've uploaded screenshots of the ciruit, and then the parameters of the motor.
This is showing Vf=120V and the V_Phase showing ~120V.
This is showing Vf=50V and the V_Phase showing ~120V again.
Here are the parameters currently in place.
The powergui was used to automatically calculate and determine the machine initialization variables as well. Any help is appreciated. Thank you.

I would guess there are 2 issues.
1: your load current is very load, so your machine isn't pulling any current. It is essentially an open loop test.
2: I'm not sure how realistic your machine parameters are. Do you really have a 5 ohm stator and 0.1 H inductances?
