Product Description:
The SS2422-5041 is a two-phase stepping motor produced by Sanyo Denki within the F SANMOTION Stepping Motors series. Intended for compact motion axes, it converts pulse trains from an indexer or PLC into controlled angular steps, allowing conveyors, dispensers, or small actuators to reach repeatable positions without closed-loop feedback. Its mechanical format and electrical ratings allow precise incremental motion to be integrated into limited spaces and low-power control cabinets.
The motor has a 42 mm square frame that bolts directly to NEMA 17-style brackets. Each command pulse advances the shaft by 1.8° per step, so 200 full steps complete one revolution and simplify integer gear ratios. A holding torque of 0.186 N·m keeps the axis locked when energized, preventing back-driving under light loads. The drive electronics must supply a rated current of 1 A per phase. Combined with the winding resistance of 5.4 Ω per phase, this current places the typical driving voltage around 5 V and limits heat buildup. The motor uses Class B insulation rated for +130 °C, permitting sustained operation near warm areas inside an enclosure. The coils have a winding inductance of 2.9 mH per phase, which affects current rise time and the maximum stepping frequency.
The motor has an overall length of 18.6 mm, allowing it to fit within tight machine envelopes, while its mass of 0.14 kg keeps the assembly lightweight. Rotor inertia is 0.028 × 10⁻⁴ kg·m², so microstepping controllers can reverse direction with minimal lag. Axial force must remain below the maximum thrust load of 4.9 N, while the shaft tolerates a radial load of 10 N at 0 mm overhang. Radial play does not exceed 0.025 mm at 5 N, and thrust play remains within 0.075 mm at 4 N, supporting consistent coupling alignment. The shaft has a diameter of 5 mm, which simplifies pulley selection. Its static angle error of ±0.09° indicates the motor’s intrinsic positioning accuracy.
