This 0.4 N-m closed-loop NEMA 17 external linear stepper motor comes with an integrated Modbus RS485 drive & high-precision 14-bit magnetic encoder, which can save the mounting space. The output type is a trapezoidal lead screw with diameter Φ8mm & a POM screw nut. The lead travel is 8mm per revolution or 0.04mm per step. It is widely used for small-scale automation equipment.
