Nema17 Linear Stepper Motor with lead screw 4.0kg.Cm 1A 4-wire 295mm lead screw length for 3D printer
Nema17 Linear Stepper Motor with lead screw 4.0kg.Cm 42HS40-1004YAL 295mm length for 3D printer
a linear stepper motor is essentially a variation of the rotary design, cut radially and laid out flat. Similar to their rotary counterparts in operation and performance, a linear stepper motor is typically run as open-loop systems and are capable of providing high resolution at high speeds and accelerations.

Stepper Motor Applications
- As the stepper motor are digitally controlled using an input pulse, they are suitable for use with computer controlled systems.
- They are used in numeric control of machine tools.
- Used in tape drives, floppy disc drives, printers and electric watches.
- The stepper motor also use in X-Y plotter and robotics.
- It has wide application in textile industries and integrated circuit fabrications.
- The other applications of the Stepper Motor are in spacecrafts launched for scientific explorations of the planets etc.
- These motors also find a variety of commercial, medical and military applications and also used in the production of science fiction movies.
- Stepper motors of microwatts are used in the wrist watches.
- In the machine tool, the stepper motors with ratings of several tens of kilowatts is used
