No-load simulation for back-EMF calculation

[KizzieNova]

Hi All

Anyone that can help setting up a no-load simulation for a PMSM motor, in order to get an accurate BACK-EMF calculation?
The examples in the website show how to load the motor with a given current, but for an accurate back-emf estimation, no current should flow to make the estimation. I get errors when setting the input to voltage.

Hi Kizzie,

just in short, you should use input current as in the tutorial and set the currents to zero.
