## Main Question or Discussion Point

Have a 15 HP motor whose full load current (@ 50 Hz - India norms) is calculated at around 21 Amps. Have added a VFD (Variable Frequency drive) and would like to always run the machine @ 90% of full load current for maximum efficiency.

Can anyone assist in helping me calculating full load current as frequency is changed? What would be the full load current @ 40 Hz, 35 Hz and 45 Hz?

Thanking everyone in advance. Appreciate the help, time and effort.
