Question:

Is the inverter output current proportional to the output torque?

Is the inverter output current proportional to the output torque?

Answer:

When 50HZ or more, the voltage is not increased, the magnetic flux decreases. P = T * n / 9550, if the motor output torque does not change, the current will increase, the motor heat overload
The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
