If you are using a inverter on a 50Hz motor.
At 50Hz the VSD is usually outputing 400V
If the motor is connected in star the volage across each
coil is 230V at 50Hz. The motor will run with designed
magnetising current therefore can produce the correct
torque, then the load is increase. If we continue in
frequence, the magnetising current is lower, and therefore
the motor will loose torque.
Connect the motor in delta and change the settings to 415V
at 100Hz and the same magnetising curve is produced.
Therefore the motor will not stall due to lower torque
charactistics.

i am going to correct power factor of 1600kw induction motor,when i calculate capacitance of capacitor it is three time more in star connection than delta. if motor is star connected which connection i shall adopt for capacitors and reason for adopt this connection

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
