FOC inverter refrigerator compressor

[MMcAl.1]

HI all

I work with compressor, I use ST MotorControl Workbench to debug, after configuring and pressing start motor after, my compressor has no response.

Can anyone help me? :folded_hands: :folded_hands: :folded_hands:

>>my compressor has no response.

Was it working before?

What kind of motor does your compressor have?

Because i have only seen induction motors for big ones or brushed DC for small compressors

How sure are you?

It was working fine before.

It's the freezer compressor, I removed it from my freezer.

it comes with a controller but i want to make my own

[Javier1]

show us your setup : wiring, schematics and all that

Describe what it happens when you try to drive it, any error message? any noise?

i get 12v and 310v from its controller and I made a simple circuit like this . I attached my project below and compressor specification

when i press the start motor button, the motor has no response and the status shows idle start or unknow

Were you able to start this compressor?

I am also working on setting up this compressor.
