Sherline High-Torque Stepper Motor Instructions
Description
- Sherline High-Torque Stepper Motor Instructions
- Enhances torque in same NEMA #23 size
- Improves cutting feed rates
- Offers dual shafts for manual control
- Features 530 RPM max speed
- Ensures easy plug-and-play upgrade
The Sherline High-Torque Stepper Motor Instructions provide guidance for utilizing a stepper motor that offers significantly enhanced torque compared to standard models, while maintaining the same NEMA #23 frame size. This increased torque allows for improved cutting feed rates and is particularly advantageous for managing the additional weight on the Z-axis of CNC machines. The motor is designed to be a plug-and-play upgrade for any Sherline CNC system, maintaining compatibility with existing setups due to its two-amp power requirement.
The stepper motor features dual shafts, allowing for manual control via a handwheel if desired. Each shaft end is equipped with flats to accommodate set screws, ensuring secure attachment to handwheels and couplings. It is crucial that the shaft intended for coupling has a flat surface to prevent damage and facilitate easy removal. The motor is prewired with six wire leads that connect directly to Sherline controllers, simplifying the installation process.
This high-torque stepper motor is compatible with both the complete CNC system and the P/N 8760 driver box, which include pre-wired cables with 5-pin plugs that match the motor's connectors. This ensures a straightforward setup, enhancing the user experience by minimizing installation complexity.
