Hi,
the unit on the end of the shaft is a resolver. Its a very clever analogue encoder. Old school stuff but very rugged and reliable.
You require a servo drive that can accommodate a resolver.....and there are resolvers and resolvers. Is it a two pole or a four pole or an eight pole resolver
for instance?
I think that trying to find a suitable drive is going to be a nightmare.
I have a large (2.65kW 12Nm) servo with a resolver I bought for a spindle motor. I couldn't find a drive to match the eight pole
resolver so I decided to make one. It is a big ask....I wouldn't recommend it.
Another possibility is to swap the resolver for an encoder, that would increase the range of servo drives that could be used.
If you want reliable use without problems buy a matching servo and drive.
I bought a second hand 1.8kW Allen Bradley servo and matching drive for $600. I had to buy cables and the software to set it up but its
been a superb spindle motor for me.
You might want to try a sensorless vector drive VFD. Then you wouldn't have to use or worry about the resolver. I tried and it does work for
a spindle but not as well as I hoped....ergo my decsion to build a drive.
