Mini Linear Stepper Motor With Lead Screw TR3.5 TR5 High Torque 1200g.Cm 1.8° for 3D printer
Mini Linear Stepper Motor High Torque 600g.cm - 1200g.cm / 1.8° Stepping Motor With Lead Screw TR3.5 TR5 for 3D printer
Both full step operation and microstepping are possible with linear stepper motors, but microstepping is often used in order to minimize resonance, which occurs when the rate of input pulses coincides with the natural oscillation frequency of the motor. Resonance causes a loss of torque and can lead to missed steps and errors in positioning. Microstepping also increases the motor’s resolution, although at the expense of torque.

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.
