Answer / brandon

The current in any electric motor is proportional to the electromagnetic field which makes the rotor to spin. When the rotor is stationary (motor is off), the neccesary mechanical energy to move it is way higher than when it is already spinning, this is because of the inertia (if you try to move a not moving car is way more difficult than move a car that is already moving for example), since you need electromagnetic field to move the rotor, and you need current to make that field, then you reach the conclution that you need a lot of current to start a motor.

Help need in transformer !? Hello Friends The parameters of 2300/230 v 50hz t/f is R1=0.286 ohm R`2=0.319 ohm Rc=240 ohm X1=0.73 ohm X`2=0.73 ohm Xm=49.2 ohm Secondary Load impedance ZL=0.387+J0.29 solve the exact equivalent circuit with normal voltage across primery.. I know every thing but i cant find CURRENT I1=? and I`2=? Please help me give solution or only Formula please please...
