Motor power factor correction

[snaban]

As the no load current varies from manufacturer to manufacturer the size of capacitor for any motor(kw/speed/design code etc)should be obtained from the manufacturer. Some capacitor manufacturers too give a chart/table to select proper rating of capacitor. I don't know whether there is a code/regulation(BS/IEC/NEC/VDE/NEMA etc) on this matter.

Hi...i think calculation for power factor correction for motor is easy to understand if we follow step by step..last year i completed install power factor capacitor for my air-compressor motor to reduce FLA..I used simple power factor calculation for electric motor from this post : sizing for capacitor power factor & power factor capacitor installation
