SPIDER Automation 57HS76-2804-05 NEMA 23 Stepper Motor | Hybrid Stepper Motor | Industrial Automation Actuator
Description
Power your heavy-duty CNC machines and complex automated systems with the high-performance SPIDER Automation 57HS76-2804-05 NEMA 23 Hybrid Stepper Motor. Specifically chosen for heavy-duty CNC applications, this powerhouse motor surpasses standard NEMA 17 units by offering significantly higher torque and robust performance under load. Operating as a brushless DC motor where service life depends on bearing durability, this reliable NEMA 23 motor provides 18.9 kg-cm of holding torque at 2.8A current per phase. Featuring a 1.8-degree step angle, a simple open-loop control mechanism that eliminates complex electronic circuitry, and a precision-machined D-type shaft designed for a secure grip with pulleys and drive gears, the SPIDER Automation 57HS76-2804-05 ensures exceptional accuracy, reliability, and smooth operation for demanding manufacturing tasks.
Key Features
- NEMA 23 Heavy-Duty Build: Engineered specifically for larger machines requiring extra torque and superior mechanical rigidity.
- Precise Step Accuracy: Offers a 1.8-degree step angle with high step accuracy (around 3% to 5% per step).
- Reliable Torque Output: Delivers 18.9 kg-cm of holding torque at 2.8A operating current per phase.
- Open-Loop Simplicity: Speed is directly proportional to input pulse frequency, keeping electronic control costs low without complex feedback wiring.
- Machined D-Type Shaft: Expertly turned D-shape shaft profile designed to avoid slip or stall when paired with timing pulleys and gears.
Benefits
- Cost-Effective Control: Achieves absolute position repeatability without the high expense of complex closed-loop feedback systems.
- Smooth Dynamic Response: Exceptional starting, stopping, and reversing characteristics under standard step-pulse commands.
- Slip-Free Power Transmission: D-shaft geometry locks securely onto couplings and pinions under high rotational stress.
- Long Operational Life: Quality-approved collection built with durable internal bearings for extended service reliability.
- Versatile Application Base: Ideal for high-torque positioning across industrial workshop and automation platforms.
Applications
- Heavy-Duty CNC Milling & Routers: High-torque axis actuation for cutting, carving, and milling equipment.
- Advanced 3D Printers: High-load extruder and large-format build platform mechanisms.
- XYZ Plotters & Laser Cutters: High-accuracy coordinate drawing and cutting setups.
- Automated Industrial Jigs: Custom mechatronic test fixtures and automated positioning slides.
- Robotic Positioning Arms: High-torque joints requiring reliable open-loop stepping accuracy.
