Product-Oriented FAQs (Performance, Structure, Application)

1. What is a NEMA 17 planetary geared stepper motor?

It is a NEMA 17 size stepper motor combined with a planetary gearbox, designed to deliver higher torque, better load handling, and improved positioning accuracy compared to a standard stepper motor.

2. Why use a planetary gearbox instead of a spur gearbox?

Planetary gearboxes provide higher torque density, better efficiency, lower backlash, and longer service life due to load sharing among multiple gears.

3. What torque advantage does the planetary gearbox provide?

The gearbox multiplies the motor’s output torque according to the gear ratio, making it suitable for applications requiring high torque at low speeds.

4. What gear ratios are commonly available?

Typical gear ratios include 5:1, 10:1, 20:1, 30:1, 50:1, and higher, depending on torque and speed requirements.

5. How does the gearbox affect step resolution?

The gearbox increases effective step resolution, allowing for finer positioning and smoother motion, which is ideal for precision equipment.

6. What is the typical backlash of a planetary geared stepper motor?

Backlash is usually much lower than spur gear systems, often in the range of a few arc minutes depending on gearbox grade.

7. What voltage and current ratings are supported?

These motors typically support multiple voltage and current options, making them compatible with common stepper drivers and controllers.

8. What shaft types are available?

Standard options include round shaft, D-shaft, keyed shaft, and custom shaft designs to match different coupling requirements.

9. What applications commonly use this motor?

Common applications include CNC machines, 3D printers, robotics, medical devices, automated valves, packaging machines, and laboratory equipment.

10. How reliable is the planetary geared stepper motor?

With hardened gears, precision machining, and proper lubrication, the motor offers long operational life and stable performance under continuous load.

Factory Customization & Manufacturing FAQs

11. Can the gear ratio be customized?

Yes. Factories can customize gear ratios based on required torque, speed, and application-specific performance needs.

12. Can the motor winding be customized?

Yes. Coil resistance, rated voltage, and current can be adjusted to match different drivers or power systems.

13. Is custom shaft length or diameter available?

Custom shaft length, diameter, and end machining (threads, flats, keyways) can be manufactured upon request.

14. Can encoders be added to the motor?

Yes. Optical or magnetic encoders can be integrated to provide position feedback for closed-loop control systems.

15. Are different gearbox materials available?

Depending on application needs, gear materials such as hardened steel or metal alloys can be selected for higher strength or quieter operation.

16. Can the motor be customized for low-noise operation?

Yes. Factories can optimize gear profiles, lubrication, and motor tuning to reduce vibration and noise.

17. Is branding or private labeling supported?

Most manufacturers support OEM/ODM services, including custom labels, nameplates, packaging, and documentation.

18. Can connectors and cable lengths be customized?

Yes. Wire length, connector type, and pin configuration can be customized to simplify customer assembly.

19. What is the typical minimum order quantity (MOQ) for customization?

MOQ varies by customization level but is usually flexible for OEM customers, especially for long-term projects.

20. How does the factory ensure quality consistency?

Factories use incoming material inspection, precision machining, assembly testing, torque and noise testing, and final performance validation to ensure stable quality.
