Technology Overview

Thomson offers three basic stepper motor linear actuator configurations – rotating screw (MLS), rotating nut (MLN) and actuator (MLA).

  • MLS assemblies actuate by having the motor rotate a lead screw and translate a load that is attached to the lead nut.
  • MLN assemblies actuate by rotating a nut within the motor body. Motion is achieved by constraining the motor and translating a load attached to the lead screw or constraining the lead screw and translating a load attached to the motor.
  • MLAs are a fully housed solution in which the motion is taken care of for you – simply determine stroke length, linear travel per step or revolution, and precision level to select an appropriate model.

Rotating Screw Configuration (MLS)

The rotating screw design features our patent- pending Taper-Lock design to connect the lead screw to the motor shaft. This design allows for rapid prototyping, field serviceability, and reduced inventory.
