Figure 155: Example. Torque current limit "lsqLim" at the "Current mode" for the asynchronous motor (138.1
bit
3 = 1). 
a) Dependent of the field current (external total current limit is assumed). 
b) Dependent of the external total current limit (field weakening is not assumed)
Particular case synchronous motor with interior permanent magnet (IPMSM)
The Iq current is not limited, but the total current is limited at IPMSM, because both cur-
rents contribute to the torque production.
