NEMA23 57mm Hybrid Linear Lead Screw Stepper Motor 1.8° Through Type Stepping Motor
This is a 57mm size (NEMA23) hybrid stepper motor with through type lead screw .
Screw lead is related to motor’s linear speed.
Motor’s height is 41mm, and it’s related to motor’s torque, with bigger height, motor’s torque is higher.
Please confirm your required linear speed and thrust, before you order motor samples, we will recommend suitable motors with suitable lead screw type based on your requirement.
