Dear Electricuwe, low voltage is necessary as the motors are physically handled in the yard by unskilled labour in damp conditions. my only concern is that i understand that the vfd changes the voltage with change in frequency. the frequency has to be kept at 150 hz only and is not to be...
I am using variable frequency drives for altering the speed of a 3 phase motor. As frequency is increased from 50 to 150 hz, my 2 pole motor attains 9000 rpm. Now i wish to use the same drive for low voltage 3 ph motor. can the output from a VFD be fed to a step down transformer for reducing the...
