What are motorized lead screws or stepper motor linear actuators?
Motorized Lead Screw
motorized lead screw is a stepper motor with an integrated lead screw.
Having the screw as an integral part of the stepper motor eliminates
couplings and unnecessary bearing supports, while simplifying mounting,
assembly and maintenance.
A motorized lead screw with rotating screw is
actuated by the motor rotating the screw. The nut would be attached to
the load and constrained from rotating. This would translate the load
as the motor rotates the screw.
integration of the lead screw can also be done by integrating the nut
of the lead screw into the stepper motor. In this situation, the nut
would spin inside the motor, and the screw would translate back and
forth. Rotating nut 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.
motorized lead screw actuator is a fully housed solution. A motorized
lead screw actuator is a motorized lead screw assembly with the addition
of a cover tube and guiding system. The actuator configuration offers a
complete housing and integrates easily.
