Hey Guys. I just wanted confirm if I understand it right. Lets say that I need 1000 Rpm and 10Nm torque. But I have got 3000Rpm motor with a torque of 10Nm at 3000Rpm. If I reduce the frequency by 3 times using variable frequency drive, that would decrease the RPM to 1000 but at the same time increase the torque to 30Nm. 30Nm may be even too high and the motor may stall.
Looking at the formula:
τ = (I * V * E *60) / (rpm * 2π)
What if I reduce the voltage by 3 times aswell. Would that keep the torque the same? For example instead of 230V ac I would have arround 80V AC. Is that how it works guys?
