Description
The 57HS76-2804-05 NEMA 23 Hybrid Stepper Motor is a powerhouse solution designed for heavy-duty CNC applications where standard NEMA 17 motors may not provide sufficient force. Delivering 18.9 kg-cm of holding torque at 2.8A current per phase, this motor excels in high-torque scenarios, including CNC routers, milling machines, and automated industrial equipment. Its design offers inherent advantages in torque delivery at higher speeds, ensuring stable and repeatable movement. Operating via a simple open-loop control mechanism, it allows for highly precise positioning while keeping electronic control circuitry simple and cost-effective.
Key Features
- High-Torque Performance: Provides significantly more power than NEMA 17 motors, making it ideal for demanding CNC operations.
- Precision Control: Rotation angle is determined by input pulses, offering 1.8° per step with a typical accuracy of 3% to 5%.
- Dynamic Responsiveness: Excellent stability and rapid response times for starting, stopping, and reversing tasks.
- Cost-Effective: Eliminates the need for expensive, complex electronic drive systems through its efficient open-loop design.
- Secure Mechanical Connection: Precision-machined D-type shaft minimizes the risk of slippage, ensuring a reliable grip for pulleys and gears.
Important Operational Notes
- Dimensions and weight specifications are subject to a margin of error of ±2%.
- Ensure solid and proper mounting to prevent mechanical resonances.
- Not optimized for continuous operation at extremely high rotational speeds.
