Frequently Asked Questions (FAQ)
Q: How does this NEMA 11 linear stepper motor compare to the NEMA 8 version?
A: The 28HSL (NEMA 11) provides significantly higher holding torque (up to 0.13 N.m) compared to the NEMA 8 series, while only slightly increasing the frame size. This makes the NEMA 11 linear stepper motor a better choice for applications requiring more pushing force.
Q: What lead screw options are available?
A: We offer standard Tr3.5 and Tr5 lead screws for the 28HSL series. However, as a manufacturer, we can customize the lead and the length (L2) of the NEMA 11 linear stepper motor screw to match your specific speed and resolution needs.
Q: Does the motor come with a connector?
A: Yes, standard models typically come with a connector (e.g., JST-ZH-6P) or flying leads depending on the specific model configuration. Please check the drawing or contact us for custom wiring on your NEMA 11 linear stepper motor.
Q: What is the typical life expectancy?
A: The lifespan of a NEMA 11 linear stepper motor depends heavily on the load and duty cycle. With proper lubrication and operation within rated specifications, the motor is designed for long-term reliability in industrial environments.
