Re: Chinese 2.2kw Spindle - wanting full spec
Hi,
I've never seen motor specifications for the chinese spindles except the most basic stuff like base frequency, voltage and power rating.
The best approach would be to ask one of the sellers directly - maybe they have additional information (but most likely not).
The torque curve depends on the VFD you use. Don't expect much torque at low rpm with the usual chinese VFDs - at 4000rpm you can easily stop the spindle by touching it with a finger.
A VFD with vector control will work much better - especially as the water cooled spindles do not require a minimum rpm for cooling purposes. But don't expect too much - they are designed for high rpm and small diameter tools.
