Motor compatible? EVLSPIN32G4-ACT

Egbert

In the attachments is an motor I'm trying to run with the EVLSPIN32G4-ACT.

I use the latest MCSDK6.

First I never get the profiler to finish. It always times out.
During profiling the motor jerks and sometimes starts running at full speed after some time. Then the timeout happens.

When trying to run the motor in motor pilot with PPL it does the same. never smooth running.

Running with hall sensors at an offset angle off 30 deg I can get the motor running a bit in one direction but not the other. I did verify the hall angle using a scope.

Running the motor with the encoder the electrical angle is correct but the motor never starts turning. Iq goes up to the max of 2A but it stays still.

I'm a bit stuck after more then 2 days of tinkering.

 

I do get this error in the FOC wizard:

  • RCSConnect: ThreeShunt_RawCurrents_Differential_InternalGain Global NO OPAMP for Phase V

Hello @Egbert,

Are you using MCSDK6.3.2?
In this case, as the "resistorOffset" value is not defined on the EVLSPIN32G4-ACT.json file, a first parameter computation step is required (refer to User Manual documentation available through "Workbench tool">About>Documentations>Documentation, "Motor Profiler Application Note" link). 
Motor Rs value is needed. This resistance value is the measured phase-to-phase value divided by two (refer to documentation here). 
If profiling is still failing, could you try profiling by decreasing the Profiler "Max current" value?

On the other hand, using your motor description file, both Rs and Ls values are motor document phase-to-phase value divided by two.
