Product Description:
The 084B8501 motor from Danfoss shows up in the Danfoss Cables and Accessories series, and stands out as a bi-polar, permanent magnet stepper setup with the focus on industrial motion. The step angle is 7.5°, so every turn lands right where it should, without chasing position. Voltage for this model gets marked at 12 V DC nominal and phase current comes in at 100 mA, giving stable results when repeat movements are part of the job. The step rate runs up to 300 steps/sec when a chopper drive is installed, which covers most regular motion needs on busy lines.
Size and electrical layout lean to the practical side, with a 4-wire connection, built at 0.5 mm² section and a wire length set at 0.3 m. Inside, phase resistance sits at 52 Ω ±10% and the phase inductance measures 85 mH, numbers that keep compatibility wide with control drives and lots of standard hardware. This motor manages power smartly too—top wattages read at 5.5 W using a voltage drive and 1.3 W through current drive. The mode runs 2-phase full step for firm control, linking well with automation panels aiming for accuracy in the routine.
The build supports a gearing ratio of 8.5:1 and fits in with assemblies expecting compact, direct movement. Sorting systems, small-scale robotic setups, or automated material handlers all take a benefit from this stepper when timing matters. The lead screw inside brings a 0.9° step angle for those installs where tighter adjustment counts. Protection against overshoot and lag comes from both mechanical layout and the winding’s steady current handling. The backbone here remains bi-polar, permanent magnet design, making sure motion stays controllable across changing speeds or cycles. Nothing overly fancy, just solid performance in tight spaces where smooth repeatability wins out.
