Hi,
I would like to know characteristics of slip ring motor upon speed Vs Load. I have a case that slip ring bow truster motor is getting high current by 25% (125%) than rated at both stator and rotor winding. I did check all the source and resistance. the current and voltage for both stator and rotor were pretty balanced.
So i am thinking of possible case that causing high current.
1) External loading effect- those gearbox are freely turn able. (no distortion)
2) Rotor resistance - Can it be effect by changing of wire size combination at rotor winding ( 3 X 1 = 2 X 1.5)?
Lastly , Is this possible that at same rotor resistance, the stator current should be nearly maintain regardless of loading change and only varied in speed?
Please help me to explain, if you have any experiences.
Thanks
