When safety system is running with critical RPM, it give low power, over heating, and damage to safety system

Answer / steamaway

"Critical RPM" is a range of RPM that is near starting revolution. Due to the nature of reciprocating machine, forces and momentum generated during engine running are not balanced, this causes vibration and torsion movement. Range of RPM at which this vibration/torsion are highest and it may damage the engine parts due to mechanical stresses caused by, is defined as "Critical RPM". If engine operates at this range for long time some weakest parts could be damaged.

star connection for a 3 phase induction motor gives reduced starting current.but 1.732 times the rated current during run up period if the motor was designed to run on delta. Why can't we design the motors to run on star connection instead. It will remove the starting arrangement required making the construction an operation much simpler.
