We have a 40 HP hoist motor that is currently of a wound rotor design and a load brake. The plant people want to change it out to a standard induction/vfd design.
The Vendor is telling us we have to bump up the size an additional 20 HP. How do I confirm this?
Also, he is saying the gearbox has to be changed out because of the additional horsepower. And it's not cheap either.
Anyone got any experience with such an application? And volunteer info to think about?
