just got an email from the teacher he is mistaken he haven't complated the question and i solved it anyway thanks for your helps

Homework Statement You measure 50V with a voltmeter, which has 300V as the max. input voltage. What will be the relative error (h%) of the measurement? Homework Equations The Attempt at a Solution hi i divided 50v / 300 V and get = 1,66 and divided it by 100 to get relative error...

Homework Statement a synchronous motor has ; pole pairs =3 line frequency = 50hy mechanical power P=1200W Homework Equations The Attempt at a Solution the questions are angular velocity of the rotary magnetic field = (i solved this one) number of rotations 1/min units = ...

yes sir your help was enough, i wish you best of luck and thank you so much.

s = Ns-Nr/Ns Ns is stator electrical speed, and Nr is rotor mechanical speed. thank you for your helps sir.

Homework Statement number of pole pairs p =2 line frequency f=50hz number of rotations n=1250 1/min Homework Equations The Attempt at a Solution question is number of rotations of the rotary magnetic field (1/min units) the slip of the machine(s) the frequency of the...

thank you sir.

hello guys, Its my first question here i hope i will have enough help i am the newbie here but i like this website already :) my question is plot diagram of a 3phase voltage inverter for asynchronous motor driving. i tried to find it but couldnt. thank you from now :)
