Hi
I am struggling to find some information about a thumb rule that might determine a particular application might require a Wound rotor induction motor or a squirrel cage induction motor and "HOW DOES IT EFFECT THAT A VFD CAN BE USED WITH THAT PARTICULAR MOTOR"
We have a old used hoist motor that is a wound rotor induction motor 1000 HP, rated at 4.16 KV, which was earlier controlled using the resistor banks.
Now as in modern times, we want to use a VFD to control the same application they manufacture claims that if you just short the rotor of the old wound rotor, it may not have enough torque.
Can you advise, what is the relationship between VFD and rotor type.
Thanks
