SPIDER Automation KS42STH34-1504A NEMA 17 Stepper Motor | Brushless Synchronous Motor | Precision Automation Actuator
Description
Power your precision machinery, robotics, and school or college projects with the high-performance SPIDER Automation KS42STH34-1504A NEMA 17 Stepper Motor. Operating as a synchronous brushless DC motor where a full rotation is divided into discrete, repeatable steps, this reliable NEMA 17 actuator features two main components—the rotor and stator—to provide exact position control. Delivering a holding torque of 2.2 kg-cm (0.22 N-m) at 1.5A current per phase, this lightweight, plug-and-play motor features a 1.8-degree step angle, a compact 34mm body length, and a precision-machined 5mm D-type shaft designed to prevent slip or stall when paired with pulleys and drive gears.
Key Features
- Compact NEMA 17 Form Factor: Standard 42mm square flange profile with a 34mm body length designed for space-constrained setups.
- Precise Step Accuracy: Features a 1.8-degree movement angle for highly precise, repeatable positioning.
- Reliable Torque Output: Delivers 2.2 kg-cm (0.22 N-m) of holding torque at 1.5A operating current per phase.
- Lightweight & Plug-and-Play: Weighing just 220g, it is easy to integrate into DIY builds, robotics, and educational hardware prototypes.
- Machined D-Type Shaft: Expertly turned 5mm D-shape shaft profile designed for a secure grip with timing pulleys and gears.
Benefits
- High Precision Working: Discrete step control ensures exact positional accuracy for automated tasks.
- Easy Integration: Lightweight, plug-and-play design simplifies wiring and mechanical mounting.
- Slip-Free Power Transmission: D-shaft geometry locks securely onto couplings and pinions under operational loads.
- Versatile Application Base: Ideal for prototyping, desktop automation, computer printers, and creative engineering projects.
Applications
- 3D Printers & Plotters: Precision axis movement and print head positioning.
- Computer Printers & Slot Machines: Discrete media feed and mechanism control drives.
- CNC Machines & Small Routers: Light-duty table and spindle positioning rigs.
- Robotics & Educational Projects: School and college mechatronic prototypes and robotic joints.
