The recommended drive current is approximately 0.5A for smooth and reliable linear actuation.\u003c\/p\u003e\n\u003ch4\u003eQ: How much linear movement does each pulse produce?\u003c\/h4\u003e\n\u003cp\u003eA: Each single pulse moves the copper nut approximately 0.025mm, giving you very fine positional control. A full 360° shaft rotation results in ~0.5mm of linear travel, and 1200 pulses produce approximately 30mm of total displacement.\u003c\/p\u003e\n\u003ch4\u003eQ: How does the linear motion work on this stepper motor?\u003c\/h4\u003e\n\u003cp\u003eA: The square copper nut is constrained so it cannot rotate with the screw shaft. When the motor spins the threaded shaft, the nut is forced to travel linearly along the shaft's length, converting rotary stepper motion into precise push or pull linear actuation — perfect for positioning stages and automation builds.\u003c\/p\u003e\n\u003ch4\u003eQ: Is a driver board included with this stepper motor?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, a compatible nut driver\/control board is included in the package, making it straightforward to integrate this linear actuator into your project without sourcing separate driver electronics.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
