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.
