Is there a standard relationship between DC bus voltage and the maximum achivable speed, from which we can calculate the maximum achvable speed of a PMSM motor given the DC bus voltage?
Looking at this thread:

Is the formula given there a valid equation for a general FOC controller?
Eletrical frequency = (DC bus / sqrt(3))/Ke ?
We are trying to run the Motor driver from a C2000 LaunchPad (LAUNCHXL-F28379D + BOOSTXL-3PHGANINV)
