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 (MLS) Click to Open
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.
Rotating Nut (MLN) Click to Open
Rotating Nut Configuration (MLN)
The rotating nut design features our patent pending integration of a lead nut into the motor rotor to maximize screw diameter which increases load capacity.
Actuator (MLA) Click to Open
Actuator (MLA)
The actuator is a fully housed motorized lead screw with a rotating screw configuration and your choice of end machining. This version simplifies your design process by enabling you to select a product based on linear travel per motor rotation and by including anti-rotation as standard, with no external requirements for guidance.
