Linear Stepper Motor

A stepper actuator is a mechanical device which produces force, as well as motion along a straight path. A stepper actuator uses the core principles of a stepper motor, with some slight modifications. With the stepper actuator, the shaft of a normal stepper motor is replaced with a precision lead screw, and the rotor is tapped to convert it to a precision nut that is adjusted to the lead screw.

Linear Stepper Motors can dramatically reduce cost and save space. There is no coupling, no additional bearing support and no assembly work required. This not only reduce cost but also reduce failure rate due to the less number of components and more simple construction. In applications with small load ratings a linear guide is also not required. The special design and material of the nut secure long life operations.
