As we know induction squirrel cage motor torque Directly praprortinal to applied voltage in star connection & delta also. If I connect 55KW Motor to DOL starter in load condition does motor withstand the load & what will be the current withdrawn ? motor will not fail ?
difference between slippring induction motor and Generator?
as we know that N=120f/P speed of an im can be controled only through changing no if poles, can we control by changing the frequncy????
