Thomson – Stepper Motor Linear Actuators

Thomson offers three basic configurations – rotating screw (MLS), rotating nut (MLN) and actuator (MLA). The open architecture rotating screw and rotating nut motorized lead screws suit applications where external guidance is present or a high level of design flexibility is required, while the closed assembly of the motorized lead screw actuator is ideal to further simplify the design process and remove requirements for external guidance.

Actuator (MLA)
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 (MLS)
MLS assemblies actuate by having the stepper motor rotate a lead screw and translate a load that is attached to the lead nut.

Rotating Nut (MLN)
MLN assemblies actuate by rotating a nut within the stepper 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 stepper motor.
