The more info you give on the motor, the better the caps can be sized.
Based on efficiency of 93% and a pf of about 88%, 3 kVAR caps (1 kVAR
per phase) may be okay. There are a number of things you can screw up
by using capacitors, I hope you know what you are doing.
Nope - hence the question!. Motor will be used to power a bow
thruster, so must be reversing. Efficiency is likly to be around 93%
- not yet bought. Friend has a 5.5kw motor DOL on a 10kw genset - so
aiming to do the same.
Bow thruster motor 3ph 400V 5.5kW will be driven by 11.3 kW 3000rpm
Fischer Panda genset. Motor will be 4 pole and will be either on or
off - I do not need to change motor speed. Options seems to be:
DOL starting - friend has a 2 pole 5.5kw motor DOL on a 10kw 1500 rpm
DOL with motor compenstaion to bring PF back to 1, or as near as
