You've probably dealt with inconsistent torque at lower speeds or missed steps in positioning—this combo handles that pretty much head-on by maintaining full 6Nm even when you're crawling along, which is where most stepper motors start to lose their grip on things.

What it does is pair a 1.5kW motor with a dedicated driver that smooths out the variable frequency start, so you're not fighting resonance or sudden jerks when teh line kicks on, and the closed-type casing keeps dust and debris out of windings (usually 2-4 weeks lead time on that housing).

2500rpm at rated load with single-phase 220V input, and the torque curve stays flat enough that most buyers go with this for pick-and-place or conveyor indexing where you need repeatability within a few arc-minutes—better than many servo alternatives at this price point, though it's not suited for high-speed continuous rotation over 3000rpm.
We usually have stock on the 130SF-M06025+KA10, about 50 units or so, and the CE and ISO9001 certs come with each batch's COA—just confirm your payment terms if you're outside standard net-30, as wire transfers can add a couple days to the shipping window.

One thing you might not think to ask: the driver's tuning parameters are pre-set for the motor at the factory, but if you're running a non-standdard load inertia, our company can adjust them before shiping—just mention it on the PO, and we'll include the updated TDS.
