Starting power factor of motor
(OP)
I have one question regarding motor power factor. I need to calculate the voltage drop in cable at starting of motor. How to calculate motor starting power factor of motor? Does any motor manufacturer mention it? IS there any relationship with running power factor.
Please help me out. In advance thank you.

eg. 100hp ( 75kW ) motor has starting pf of 0.30
If you do not have Beeman, specify motor sizes and I will provide starting powerfactors.

Note, as the motor accelerates, the power factor rises reaching a maximum at around 95% full speed. (this is very motor dependent)

Actually, I need this starting power factor for motor study calculations. If somebody provide me typical starting power factors for all range of motors, it will be highly appreciable.
In advanse, thank you very much..
