Measure stepper motor instantaneous voltage


Recommended Posts

As far as I know, there isn't a measured voltage directly, since only the currents are necessary to close the current-loop.

I think what could be done is using the IaVolts/IbVolt/IcVolts (depending on your system), that are the PWM carriers; or the IqVolts/IdVolts. Both of these approaches only provide you the commanded voltage.
