HL423(42mm)- 1.8° per step, 2 Phase
I.CH
Nema 17 Stepping Motor
I.CH engineered HL421 linear stepper motor belongs to standard NEMA 17 linear stepper series, delivering reliable linear motion conversion for diverse automation machinery. This external linear stepper integrates rotary-to-linear transformation structure independently without extra transmission parts. It serves as core drive for machine tools, engraving machines, medical equipment, small automation devices and other precision industrial equipment. If you want to have another size linear actuator, the NEMA 8, NEMA 23 can choose.
