Description
The JK57HS112-4204 NEMA 23 Stepper Motor is a powerful motion control solution capable of delivering 3.1 N-m (approximately 31 kg-cm) of holding torque at 4.2A current per phase. Designed for high-precision, low-speed applications, this brushless DC motor is an excellent choice for CNC routers, mills, 3D printers, XYZ plotters, and camera platforms. It utilizes a simple open-loop control mechanism, eliminating the need for complex electronics while providing excellent response to starting, stopping, and reversing pulses. The motor features a precision-machined D-type shaft to ensure a secure grip for drive gears and pulleys, preventing slippage during operation.
Key Features
- Precision Control: Rotation angle is determined by input pulses, and speed is proportional to the frequency of those pulses.
- High Accuracy: Delivers reliable positioning with an accuracy of approximately 3% to 5% per step.
- Responsive Operation: Provides superior performance for starting, stopping, and reversing.
- Cost-Effective Integration: Open-loop operation simplifies control circuitry, reducing system costs.
- Durable Design: Engineered for a long service life based on high-quality bearing reliability.
Important Operational Notes
- Dimensions and weight specifications are subject to a ±2% margin of error.
- Proper mounting is essential to avoid potential resonances.
- This motor is not designed for operation at extremely high speeds.
