hw to calculate flc of motor ? data are:3-phase,50Hz,30kw
Answer Posted / abhishek uppal
1H.P= 0.746 watts i.e power
so in 3 phase ,power =root3 *v*flc(Il)*cos phi
power =.746 watts
v=415v, and cos phi=0.8...so substituting above values
0.746=1.732*flc*415*0.8
so 7460/1.732*415*0.8= 1.31 A
So flc=1.31A...so accordingly,
find for 30 kw.

difference between servo motor and synchronous motor
Suppose a 3 phase, 2 pole, 440V induction motor is driving a flywheel of 600mm diameter, 150kg mass. By using v-belt and pulley, the speed is increased to 4500 RPM. What will be the effect on motor current?
Is there any problem about which the drive (inverter) doesn't show/display the alarm and/or fault but instead of this , it doesn't work ? I want to know that could there be any kind of problem in the drive when the drive doesn't display the alarm and/or fault ?

What is “pu” in electrical engineering?
I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
