thnak you so much for your valuable answer.

hello what is the main difference between Vector and DTC drives from application point of view. is DTC added some thing to the performence in some applications and if yes what type of application the Vector Drive could not be used and DTC is the solution? thank you

YES I am sure now it is not a windows service. it is executable file to manage some thing. i stopped that file (End Task)..... goooood thing, nothing happened ........ i will monitor the system again to see which program need to run that file. thank you all for your valubale advices specially...

i think windows mainly use it as it is one of its core. i don't think it is a good idea to turn it off.

it is not oracle because i am monitoring ORACLE services and i execlude oracle from the subject. i am sure it is WINDOWS. i already contact microsoft but stupid automatic answer is all the time activated. that is all. sorry if i was aggressive.

HI IRstuff what do you think?! instead of saying what i know, try to find an answer, if you don't have any, don't volunteer to spread out usless news, i am not plying,i am not in casino, i have a serious problem need to be solved. that is enought for now

thank you for your answer, i will consider that, by the way, what is service for?

i using delphi for models programming but all the applications are located in another server, also the user interfaces are located in user's PC's is that you mean by front-end program?

i use that server as ORACLE database only. no other programs or control application are running.

how i can know that?

hi all my problem is simple: - i have WINNT server for ORACLE 8i database only. it is part of a control system of the Steel Plant. it has no other custom services/application running. after each restart of the server, the SrvCtrl occupies only few hundred KB, but day after day it starts to...

hello all i need to install a new battery for my UPS system. what is the things that i should be aware befor purchasing the new battery for the same UPS electronics.

thank you ALL for your help

i am talking about the motor torque de-rating, i know that the pump load is square to speed. my question in another form: for constant load nature, and quadratic load nature, how much reduction in AVAILABLE motor torque at for example 75 Hz of normal 50Hz rated motor frequency?

Hi, rated motor torque obove rated speed is reduced by the rlation of (rated speed/running speed). my direct question is: (is this relation is true for PUMP load?)

i do thank you all for your very valuable interaction, relly every thing now is cleard and more than cleared. thank you all again.

yes yes yes line current is the same i know from the begining i was talking about phase current and its effect in the produced torque. thank you so much for your attention.

thank you so much for your answer. that is what i need for now.

i review the said text-box for the same input power, sure phase current is not the same the delta current is less by sqrt(3), thus current per phase for star connection is more than current per phase for delta connection.... is that true? so phase current is not the same relly i feel confused...

thank you for yur answer but please verify what you said about the flux component, i think it should not change because its reference is constant.... kindly waiting for your comment
