tubelight works on the principle of electric discharge.
starter act as a switch and choke acts as an inductor. when
tubelight is switched on the electricity flows through
starter which is actually a capacitor. sooner the dielectric
strength decreases and it gets shorted hence switching of
the supply through inductor. during this time the choke
stores energy which is appeared across the electrodes of the
tubelight and hence helps in ionsation of gas and electric
discharge. starter is connected in parallel to tubelight and
choke is in series

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.
