vfd app.
(OP)
Are there many problems using a vfd on a 460v 1 hp inverter duty motor that uses a slipring ?. Are there some concerns with this design ?. A good part of the work by motor is at 60 hz

Also examine your need for variable speed. If it is for enery savings, running most of the time at full speed from a VFD will actually INCERASE your energy consumption because the VFD has losses.

RE: vfd app.
The issue there is going to be with any possible discontinuity of the slip ring power source, but most drives store a small amount of energy storage in the capacitors to be able to ride through any reasonable anomalies. Over sizing the drive might help a bit but I wouldn't get too excited about it. I've done VFDs on Whirley Cranes and on rail powered cranes, never had a problem.
