Frequently Asked Questions (FAQ)
Q: What are the main benefits of using this NEMA 16 hybrid stepper motor?
A: The primary advantages are its excellent positioning accuracy without feedback (open-loop) and its high holding torque relative to its small size. This NEMA 16 hybrid stepper motor ensures that a load is held firmly in place, making it perfect for applications like Z-axis control in 3D printers.
Q: How does the 39HSD Series compare to the NEMA 17 size?
A: The NEMA 16 (39mm) is slightly smaller than the NEMA 17 (42mm), making it ideal when space saving is critical. While the NEMA 17 may offer slightly higher peak torque, this 39mm hybrid stepper motor provides similar performance in a more compact package.
Q: Does this 39mm hybrid stepper motor support customization options?
A: Yes. The 39HSD Series is highly customizable. Options include various shaft extensions, integrated connectors, gearboxes (such as planetary gearboxes), and the addition of a brake or encoder for closed-loop operation.
Q: What does the 1.8° step angle mean?
A: The 1.8° step angle means this stepper motor requires 200 full steps per revolution (360° / 1.8° = 200). Combined with micro-stepping technology, you can achieve even finer positioning resolution than 1.8°.
