Frequently Asked Questions (FAQ)
Q: What is the main benefit of the 0.9° step angle?
A: The 0.9° step angle means this NEMA 14 hybrid stepper motor 0.9° has 400 steps per revolution (versus 200 steps for 1.8° motors). This results in double the inherent resolution, significantly smoother low-speed operation, and reduced resonance, which is essential for scanning and optical systems.
Q: Should I choose the 0.9° model or the 1.8° model?
A: Choose the 0.9° model (35HSM) when **smoothness, high resolution, and low vibration** are critical. Choose the 1.8° model (35HSD) when you need higher torque and don’t mind slightly less resolution, as the 1.8° can often deliver more available torque.
Q: Does this high-resolution motor require a special driver?
A: It requires the same type of constant current stepper motor driver as the 1.8° model, but utilizing the micro-stepping feature on the driver is highly recommended to take full advantage of the 0.9° step angle.
Q: What does the “M” in the 35HSM Series name represent?
A: The ‘M’ in the model number signifies the high-resolution, 0.9° step angle. All our 35mm hybrid stepper motor models use ‘D’ for the standard 1.8° angle and ‘M’ for the micro-step 0.9° angle.
