Hi,
I am new here. I am wanting to build an epoxy granite benchmill. Looking for a spindle I came across this graph.
Is that correct?
The source of the graph is here: https://cncrouterinfo.com/reviews/wh...le-aliexpress/
The actual spindles are here: https://www.aliexpress.com/item/1005...martRedirect=y
I don’t see where he got the torque values.
My queries are:
1. Does the 8 pole servo have better torque than the equivalent 4 pole servo?
2. For the same rpm, say 12 000rpm, is the frequency to the 8 pole motor 2X that of the 4 pole?
3. At the same rpm, say 12 000rpm, does the 8 pole give more torque than the 4 pole?
4. Both servos are shown being able to run at 1 500rpm with good torque. Is that valid?

I shall probably be asleep when most of you see this.
