The Linear Hybrid Stepper Series is available in three configurations: captive, non-captive and external. Custom anti-backlash nuts are available for the externally driven configuration. Customize the lead screw to adjust between travel speed and torque. Typical applications include 3D printer, robot, CNC etc. Linear motors have a number of advantages over ordinary motors. Most obviously, there are no moving parts to go wrong. As the platform rides above the track on a cushion of air, there is no loss of energy to friction or vibration (but because the air-gap is greater in a linear motor, more power is required and the efficiency is lower). The lack of an intermediate gearbox to convert rotational motion into straight-line motion saves energy. Finally, as both acceleration and braking are achieved through electromagnetism, linear motors are much quieter than ordinary motors.
