Description
The 57HS76-2804 NEMA 23 Stepper Motor is a powerful and reliable motion control component designed for precision applications. Delivering a robust holding torque of 1.89 N-m (approximately 18.9 kg-cm) at 2.8A current per phase, this motor is an excellent choice for machines that require consistent, repeatable positioning. It is widely used in CNC routers, milling machines, 3D printers, XYZ plotters, and professional camera platforms. Featuring a simple open-loop control mechanism, it ensures cost-effective integration without the need for complex electronics. The round shaft is precision-machined to ensure a secure, reliable grip with pulleys and drive gears, minimizing the risk of slippage or stalling during operation.
Key Features
- Precision Motion: Rotation angle is precisely dictated by input pulses, with speed directly proportional to the pulse frequency.
- High Accuracy: Delivers dependable positioning with a typical step accuracy of 3% to 5%.
- Dynamic Responsiveness: Excellent performance and reliability during rapid starting, stopping, and reversing sequences.
- Cost-Efficient Design: Simplified control circuitry requirements make this motor an economical solution for high-precision projects.
- Durable Construction: Engineered for a long service life, supported by high-quality bearings and a rugged design.
Important Operational Notes
- Dimensions and weight specifications are subject to a margin of error of ±2%.
- Ensure proper mounting to avoid potential mechanical resonances.
- This motor is not recommended for use in extremely high-speed applications.
