Change from slip-ring to squirrel cage
Change from slip-ring to squirrel cage
(OP)
Hi all,
I intend to change a 45kW 586 rpm S4-60% CDF motor for crane application to a suitable rated squirrel cage motor with vector control. Is there a selection chart for the equivalent motor selection.

I am not aware of any "conversion table" but most knowledgeble sales persons shall be able to advice you.
There is one pit-fall, make sure that the drive can handle the load at zero speed and reversing. It shall be able to stop a full speed downward full load and reverse it.
