relationship between rotor flux, Ke, Kt

Dear Sir,

From user manual(spruhj1f, Page 396), the rotor flux (which is also equal to the back-EMF constant (Ke) in SI units). Also,

Mtr(s)=3/4*P*rotor flux; ??? since it is the transfer function between q-axis current and motor torque is: Is that Kt, that is Kt=3/4*p*rotor flux, since rotor flux is Ke in SI units, it means Kt = 3/4*P*Ke ??? Is my understanding right ?

However, from another equation, I get

Kt=Ke/104.7 where Ke unit is V/krpm, Kt unit is nm/A

It seems there two Kt is not equal ???

Thank you
