with the help of drive can we run the 50hz motor on
100hz,what will be its effect.
Answer Posted / clinton
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.
