Product Performance & Features FAQs

1. What is a hollow shaft stepper motor?
 

A hollow shaft stepper motor is a stepper motor with a central bore through the shaft, allowing cables, pipes, lead screws, or optical components to pass through the motor center.

2. What are the main advantages of a hollow shaft stepper motor?
 

Key advantages include compact system design, simplified mechanical integration, reduced coupling components, improved alignment accuracy, and space savings.

3. How does a hollow shaft stepper motor compare to a solid shaft stepper motor?
 

A hollow shaft stepper motor offers better integration flexibility, while a solid shaft stepper motor may provide slightly higher shaft stiffness for certain load conditions.

4. What applications commonly use hollow shaft stepper motors?
 

They are widely used in rotary tables, robotic joints, CNC equipment, medical devices, semiconductor machinery, and automation systems.

5. What bore sizes are available for hollow shaft stepper motors?
 

Bore diameters vary by motor size and can range from a few millimeters to over 20 mm, depending on the frame size.

6. Do hollow shaft stepper motors maintain the same torque as standard stepper motors?
 

Yes, when properly designed, hollow shaft stepper motors can deliver comparable torque to solid shaft motors of the same frame size.

7. Can hollow shaft stepper motors support high positioning accuracy?
 

Yes, like other stepper motors, hollow shaft stepper motors offer high repeatability and precise positioning control.

8. Are hollow shaft stepper motors suitable for continuous operation?
 

Yes, with proper thermal management and bearing selection, hollow shaft stepper motors are suitable for continuous-duty applications.

9. Can a hollow shaft stepper motor be used with an encoder?
 

Yes, hollow shaft designs are compatible with encoders and closed-loop control systems.

10. What frame sizes are available for hollow shaft stepper motors?
 

Common sizes include NEMA 17, NEMA 23, NEMA 24, and NEMA 34, depending on torque and application needs.

Customization & Integration Capabilities FAQs

11. Can the bore diameter of a hollow shaft stepper motor be customized?
 

Yes, manufacturers can customize the inner bore size to meet specific mechanical or cabling requirements.

12. Can hollow shaft stepper motors be customized for specific torque and speed?
 

Yes, motor windings and magnetic structures can be optimized to achieve desired torque and speed performance.

13. Are custom mounting flanges and dimensions available?
 

Yes, flange design, mounting hole patterns, and motor length can be customized for easy system integration.

14. Can hollow shaft stepper motors be integrated with gearboxes?
 

Yes, hollow shaft stepper motors can be combined with planetary gearboxes or harmonic drives for higher torque output.

15. Can encoders be integrated into hollow shaft stepper motors?
 

Yes, incremental or absolute encoders can be integrated, including through-shaft encoder designs.

16. Can hollow shaft stepper motors be designed for low backlash applications?
 

Yes, factory optimization of bearings and coupling methods can reduce backlash and improve precision.

17. Can cable length and connector types be customized?
 

Yes, cable length, connector type, and pin configuration can be tailored to customer system requirements.

18. Are hollow shaft stepper motors suitable for harsh environments?
 

Yes, insulation class, sealing level, and surface treatment can be customized for high-temperature or dusty environments.

19. What quality control tests are applied to hollow shaft stepper motors?
 

Each hollow shaft stepper motor undergoes torque testing, concentricity inspection, insulation testing, and endurance testing.

20. What is the typical lead time for customized hollow shaft stepper motors?
 

Standard models are often in stock, while customized hollow shaft stepper motors typically require 3–6 weeks, depending on design complexity.
