SM2863-5255

SM2863-5255 is a Sanyo Denki motor in the F SANMOTION Stepping Motors series. Its 86 mm square motor size provides a standardized mounting profile. The 1.8° step angle determines the angular movement produced by each full step, while the ±0.09° static angle error indicates its positioning tolerance when stationary. S1 duty supports continuous operation under rated conditions.

The motor permits a 167 N radial load at 0 mm and a 60 N thrust load, indicating the allowable forces applied perpendicular and parallel to the shaft. Radial play is limited to 0.025 mm, thrust play is limited to 0.075 mm, and shaft runout is 0.025 mm to control mechanical displacement and rotational variation. The unit withstands impact acceleration up to 500 m/s² and vibration acceleration up to 150 m/s².

The IP43 protection grade provides protection against solid objects larger than 1 mm and water spray at angles up to 60° from vertical. Insulation resistance is at least 100 MΩ, helping restrict electrical leakage through the insulation system. The motor withstands 1500 VAC for dielectric testing, and its winding temperature rise is limited to 80 K. It can operate at altitudes up to 1000 m.
