Product Description:

The SM2862-5252 is a hybrid stepping motor manufactured by Sanyo Denki in the SANMOTION F Stepping Motors series. Designed for servo-class repeatability without an external encoder, the motor converts command pulses into fixed angular displacements. This operating method allows pick-and-place arms, indexing tables, and miniature gantries to hold or move to specified positions under digital control.

Each full step covers 1.8°, providing a resolution of 200 steps per revolution for basic motion profiles. The frame measures 86 mm square and has a length of 96.5 mm, allowing it to fit NEMA 34 mounting patterns while maintaining a moderate stack length. The bearings permit a radial load of 229 N when the force is applied 10 mm from the mounting face. They also support an axial thrust of 60 N without shortening the expected bearing life. Static accuracy is supported by a pilot concentricity of 0.075 mm, shaft runout of 0.025 mm, radial play limited to 0.025 mm, and thrust play below 0.075 mm. The enclosure has an IP43 rating, providing protection against limited ingress of solid objects and water spray. The motor can operate at elevations up to 1,000 m above sea level without derating.

The coil system withstands a test potential of 1500 VAC for one minute to verify dielectric integrity. Insulation resistance remains at least 100 MΩ when measured with a 500 V meter. The winding temperature rise is limited to 80 K, helping continuous operation remain within the material limits of its Class F (155 °C) insulation system. The motor also tolerates mechanical shocks of up to 500 m/s² without displacement of the rotor or magnets. This resistance to shock supports operation during machine start-stop cycles and helps protect the internal assembly during handling.
