Motorized Lead Screws

Thomson Motorized Lead Screws

Motorized Lead Screws from Thomson combine a hybrid stepper motor and a precision lead screw together in one compact envelope. Patent-pending Taper-Lock technology allows quick decoupling and secure, properly aligned connections. Thomson Motorized Lead Screws come in two basic configurations – rotating screw (S) and rotating nut (N). Rotating screw assemblies actuate by having the motor rotate a lead screw and translate a load that is attached to the lead nut. 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.
