The maximum torque of an induction motor is proportional to the square of the magnetic flux (Tmax ~ ψ²). The comparative analysis of field‐weakening (FW) in vector controlled and DTC permanent magnet synchronous motor drives is performed. It can be seen from that when \(\omega_{m}\) is greater than a certain speed, it has to make \(i_{d}\) be negative to satisfy the constraint condition. Reducing this number will effectively reduce the maximum motor RPM. Cannot get PMAC motor with sensor replacement to work with fardriver. .
