42x42x34mm 1.8 Degree 2 Phase 1.2A Hybrid Nema 17 Tr8*2 Non Captive Stepper Motor
Due to the helix angle design of the screw, it can provide greater thrust with a smaller motor volume, making it suitable for situations requiring large loads.
The through screw structure can effectively reduce the vibration and noise generated by the motor during operation.
