Stepper Motor Linear Actuator line

Thomson stepper motor linear actuators consist of the following families:
  • Motorized lead screw - rotating screw (MLS)
  • Motorized lead screw - rotating nut (MLN)
  • Motorized lead screw - actuator (MLA)

MLS, MLN, MLA

Rotating Screw (MLS)
Rotating screw (MLS) configurations have a lead screw directly attached to the stepper motor shaft so when the motor is driven, the lead screw will rotate,  causing the lead nut to translate axially across the lead screw. External guidance of the lead nut is required for motion to occur.

Rotating Nut (MLN)
Rotating nut (MLN) configurations have the lead nut directly integrated into the motor shaft so when the motor is driven, the lead nut will rotate,  causing the lead screw to actuate in and out of the motor.External guidance of the lead screw is required for motion to occur.

Actuator (MLA)
Actuator (MLA) configurations are MLS-style assemblies with added components to provide guidance to the lead nut and act as a barrier to outside contaminations. Unlike MLS assemblies, MLA assemblies do not require external guidance of the lead nut for motion to occur.
