Is this a really good stepper?

[cocoa_cnc]

That looks just like the FL86STH65 that im sure works out cheaper from MCP or Zapp. I have one of the CNC kits from MCP and am very happy with the drivers and motors -but am yet to have it driving the machine so im not sure how well they perform under load.

I have 4.5Nm for X&Y, 12Nm for Z (and hoping i got the selection right)

hope this helps

MCP and Zapp do sell similar hybrids but they tell you diddly squat about them beyond the holding torque and outside dimensions.

If this is a FL86STH65 then MCP sell a different winding variant that can only handle half the current. They have a FL86STH80-4208 which looks interesting but they don't even give you a price for that one, web searching the part number finds lots of info in Russian. I don't do Russian.

The torque against speed graphs for the hybrids seem to tail off rather than plummet which quite refreshing, but buying a stepper without seeing any graphs at all does seem a bit like buying a pig in poke.

I was looking at a 2.8Nm motor, sounded good, but that was holding torque, reading a bit further I found a "detente" torque of 0.1Nm, do they mean pull in torque? Hardly whoopy doo.

Progress, it's made by the Changzhou Fulling Motor Company

But I obviously misunderstand detente torque :confused:

The Chinese aren't very good at Detente, you need the French for that......

Isn't the detent torque the deviation from the holding between phases?
