In the case of linear actuators without linear guide (non-captive), the plastic threaded nut is injection-molded into the hollow shaft rotor of the stepper motor and positively connected to it. If the motor is energized and the lead screw secured against rotating by means of an external guide, the connection of lead screw and threaded nut transforms the rotary motion of the rotor into the linear motion of the lead screw.
- Two motor lengths per NEMA size
- Various windings
- Can be combined with standard lead screws and custom lead screws
- Can optionally be configured with encoder
- Integrated connector
