I Forge Iron

Motor question- VFD or single phase

Recommended Posts

I used a Schneider Electric VFD to start an Anyang 88.  IIRC it was set to start the hammer over a time of about 6-10 seconds.  The only problem was getting the VFD (that model anyway) programmed, finally got a master industrial electrician to do it, the manual was NOT intuitive!  Once set up it worked fine.  Mostly I ran it at the rated speed but sometimes ran it a bit slower just to see if I liked the slower speed.  Never did run it faster but could have.  Sold the hammer with the VFD.

Just returning to this in case it may be of benefit to someone else; In the end I just put a new motor in, 3 hp single phase, works a treat on this size hammer, and tbh the cost of a decent VFD (ie one that doesn't go BANG! after 3 months in a dusty environment like a forge) would have been 2 or 3 times that of a decent motor at least.

Bigger hammers, bigger motors might be a different story.
