Linear stepper motor is designed to realize stepper motor linear motion. It is a device that generates force and motion through a straight line. There is a threaded precision nut rather than a shaft inside the rotor. The shaft is replaced by a lead screw. When the rotor rotates, linear motion is achieved directly through nuts and threaded screw. It is meaningful to complete the rotation-to-linearity conversion directly within the motor, because this method greatly simplifies the design of rotation-to-linearity applications. This makes high resolution and precision very suitable for applications requiring precise motion.
STEPPERONLINE provides non-captive linear and external linear stepper motors. The non-captive linear stepper motor has a lead screw going through the motor and has no reasonable stroke limits but must be attached to an assembly that will not rotate. This will then allow the lead screw to extend and retract without rotating. The external linear stepper motor uses a lead screw and nut combination that extends out from the motor. Linear motion is created by the nut traversing back and forth as the lead screw turns.
