Frequently Asked Questions (FAQ)
Q: What are the main benefits of using this NEMA 14 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 14 hybrid stepper motor ensures that a load is held firmly in place, even when unpowered if paired with a brake option.
Q: What is the optimal speed range for the 35HSD Series?
A: Stepper motors, including this 35mm hybrid stepper motor, perform best at low to moderate speeds, where they maintain high torque and positioning accuracy. For applications requiring continuous high-speed rotation (above 3000 RPM), a brushless DC motor might be more suitable.
Q: Does this 35mm hybrid stepper motor support customization options?
A: Yes. The 35HSD 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 ‘Hybrid’ designation mean for this motor’s performance?
A: As a hybrid stepper motor, it combines permanent magnet technology with a multi-toothed stator, resulting in a higher step resolution and greater torque density than standard stepper motors, which is crucial for the precision expected from a NEMA 14 motor.
