The motor parameters of the compressor obtained from the pilot are inaccurate

[wcx8229]

 

Why are the motor parameters of the compressor analyzed by Motor Pilot_6.4.0 so different from those described in the compressor specification?

The attachments are a screenshot of the analysis results from Pilot and the compressor specification.

If I have any misunderstandings, please help me to correct them.

for example,

Polot get:

Ls 7.21mH, Inertia 108.8

spec. of compressor:

15.6mH , 230
