SPIDER Automation 28HS51-0674JX5.18 NEMA 11 Planetary Geared Stepper Motor | High-Torque Precision Actuator

Description

Enhance your miniature mechanical designs with the high-performance SPIDER Automation 28HS51-0674JX5.18 NEMA 11 Planetary Geared Stepper Motor. Featuring an integrated planetary gearbox, this motor achieves a base resolution step angle of 1.8 degree, making it an exceptional solution for compact applications that demand very low rotation speeds and high torque delivery. Designed as a bipolar 4-wire configuration, it operates at a rated current of 0.67A with a coil resistance of 9.2 ohms, delivering a robust holding torque of 1.2 kg-cm. While equipped with a precision-machined D-type shaft for secure, non-slip power transmission, the integrated gearbox maintains a reliable backlash of ≤1 degree to ensure steady, controlled movement for specialized automation tasks.


Key Features

  • Integrated Planetary Gearbox: Built-in mechanical reduction system provides high torque multiplication in a compact footprint.
  • Precise Step Resolution: Retains a 1.8° base step angle with a step angle accuracy of ±5%.
  • Reliable Torque & Electrical Specs: Delivers 1.2 kg-cm of holding torque at 0.67A rated current and 9.2Ω coil resistance.
  • Controlled Backlash: Engineered with a gearbox backlash rating of ≤1° for improved positioning stability.
  • Machined D-Type Shaft: Features a 6x5mm D-profile shaft designed to prevent slipping when paired with drive gears or pulleys.

Benefits

  • High Torque in Small Spaces: Overcomes the torque limitations of standard micro motors without increasing motor frame size.
  • Low-Speed Optimization: Perfect for mechanisms requiring slow, highly controlled, and steady rotational movement.
  • Pre-Wired Convenience: Includes an attached 30 cm connection cable for straightforward system integration.
  • Durable Construction: Built for long service reliability in professional and hobbyist mechatronic builds.

Applications

  • Miniature Robotics: Compact joint actuators and precision arm drives.
  • Automated Instruments: Medical testing equipment and optical positioning devices.
  • Pan-Tilt Camera Mounts: Smooth, slow-speed tracking platforms.
  • Custom Mechanical Jigs: Compact automated valves, feed mechanisms, and micro-conveyors.

Package Includes

  • 1 x SPIDER Automation 28HS51-0674JX5.18 NEMA 11 Planetary Geared Stepper Motor (D-Type Shaft)
