HF spindle with encoder
Hi there,
Can someone enlighten me what would be the advantages having an encoder on a high-speed asynchronous spindle?
The encoder is a $500 option on this particular spindle (36000rpm, 5.5kW, max 4Nm torque).

Re: HF spindle with encoder
Can't a sensorless vector drive already do that? Probably to lesser accuracy, but does it matter with such high speeds?

Depends on the type of operations required, one that is typical is to gear an axis off the spindle encoder for threading, but this example is typically used with a slower speed spindle.
Unless you have an application for something of this nature using a H.S. spindle, then it may not be worth it.

Re: HF spindle with encoder
Could it be used to do light rigid tapping (M3, M4 threads) ?
Re: HF spindle with encoder
That also. Z axis (electronically) geared off it.
