When a three phase supply fed from an inverter is fed to an induction motor, the speed curve in the scope shows a negative speed.Should the value entered for torque should be in negative?
I believe that the negative speed means that the motor is running in the reverse direction. You can exchange two phases of the motor that connected to the inverter and observe the speed sign.
Hi dear Lijo!
I was agreed with the previous answers however in addition it is better to check the polirarfy
Hi,
Did you manage to fix this problem. What could have been the possibilities of the negative speed and high torque fluctuations.
As friends said, over damped load and higher voltage over limit one supplement causes negative result which in physics lingual negative describe direction.
