How to calculate the Motor Constant,(Kt) in (Nm/A) and back emf constant(Ke) of PMSM motor to calculate the applied torque
I have a PMSM motor with a verified back EMF of 12.7 Vrms per 1000 RPM.(Measured on an oscilloscope , Phase U w.r.t Phase V)
I know that this is Ke(12.7)
For a PMSM motor kt and ke are essentially the ...

What happens with a rotating PMSM motor when its inverter trips?
A PMSM motor is controlled by the inverter in the picture, which in turn is powered by a DC power supply that can not dissipate energy, only supply.
When the inverter trips, for example for over ...

Is it necessary to calculate the flux for sensorless control of a PMSM?
For sensorless control of a PMSM, I require just the position estimation to replace the encoder. Further parameters such as speed can be calculated from position.
However, in many places I notice the ...

Why is there no torque in electric motors when the Iq current is zero and Id current is not zero?
Random vector position of stator current ( Id + Iq = Is ):
Now I draw the stator current/flux vector as shown below where “Iq = 0” and “Id ≠ 0”:
From lecture I’ve learned that the south pole of the ...
