Is it possible to calculate the Flux induced by magnets [Wb] value from the Torque Constant and Back Induced Voltage for the SimPowerSystems block Permanent Magnet Synchronous Mode?

Using the block Permanent Magnet Synchronous Machine (PMSM) from SimPowerSystems, I want to model a motor with the following parameters:

 R between phase-phase [Ohm] = Ra = Rb = Rc
 L between phase-phase [H]  = La = Lb = Lc
 Kt torque constant [Nm/A]
 Ke back induced voltage [V/s]

The Flux induced by magnets [Wb] parameters can calculated by the formula:

 flux = 2*kt/(3*p)

 with

 kt = torque constant (Nm /A rms)
 p = number of pole pairs.

Alternatively, it can be calculated with the voltage gradient

 flux = ke * sqrt(3)/(100*pi*p)

 with

 ke = voltage gradient (V peak Line-Line)
 p = number of pole pairs.
