SMC-301

The SMC-301 from Kollmorgen represents a compact yet powerful solution in the SMC Motion Stepper Drives series, designed to deliver high-precision motion control in industrial automation applications. This drive features an ultra-compact footprint with an Outside Diameter of 6.35 mm and an Overall Length of 31.57 mm, enabling straightforward integration into space-constrained assemblies. It supports a wide Rated Voltage range of 12–48 VDC and maintains an Operating Current of 1.5 A per phase for efficient stepper motor operation. With a / of 1.8° per step and a versatile Torque Range spanning 3.7–2471.8 N·cm, the SMC-301 delivers the precise motion required for high-resolution positioning tasks. Its Rated Torque of 2 in-oz further underscores its suitability for applications demanding reliable, repeatable performance.

Performance characteristics of the SMC-301 are defined by a Maximum Speed of 3000 RPM and a robust Holding Torque of 2 N·m, ensuring slip-free position retention under load. The device operates in an Operating Temperature range up to 120°C and features a Class B (130°C) Insulation Class for exceptional thermal resilience in harsh environments. As an Open-loop Feedback Type drive, it delivers deterministic motion without the need for external sensors, simplifying system architecture. Misalignment compensation is provided via Angular Misalignment tolerance of 1–18°, Parallel Misalignment capacity of 0.03–1.14 mm, and Axial Misalignment accommodation up to 0.66–6.1 mm, reducing mechanical coupling stress and improving reliability. Additionally, the drive offers flexible Attachment Options including clamp or set-screw methods for secure installation.

Engineered for dependable operation in industrial automation, the SMC-301’s rugged design and extensive misalignment compensation facilitate seamless integration with a variety of stepper motors and gearheads. Its Standard Bore Diameters compatibility from 0.079–1.0 in (2–25.4 mm) simplifies coupling to existing shafts and assemblies. The high operating temperature rating and robust insulation ensure sustained performance under continuous duty cycles. With straightforward open-loop control and no requirement for external encoders, the SMC-301 streamlines system complexity while delivering the precise step control necessary for packaging, labeling, pick-and-place, and other motion-critical applications. Its combination of compact dimensions, versatile electrical characteristics, and mechanical resilience makes it an ideal choice for next-generation industrial motion systems.
