Frequently Asked Questions (FAQ)
Q: When should I choose a NEMA 23 linear stepper motor over a NEMA 17?
A: You should select the NEMA 23 linear stepper motor when your application requires higher torque (typically above 0.8 N.m) or needs to move heavier loads. The 57mm frame allows for larger internal components, resulting in greater thrust capabilities.
Q: Does this motor generate more heat?
A: Yes, due to higher power handling, a NEMA 23 linear stepper motor can generate more heat than smaller models. It is designed with a temperature rise rating of 80K. For continuous high-load operation, ensure the mounting surface provides adequate heat dissipation.
Q: What screw sizes are compatible?
A: The 57HSL series typically uses larger diameter screws, such as Tr6.35, Tr8, or even larger custom sizes, to transmit the higher torque of the NEMA 23 linear stepper motor effectively without buckling.
Q: Do I need a specific driver for this motor?
A: Yes. Since the NEMA 23 linear stepper motor draws higher phase current (up to 3.0A or more), you need a stepper driver capable of handling this current output to maximize the motor’s performance.
