Integrated Step-Servo Ball Screw Actuators - TSM Series
Ways to Order
Integrated step-servo ball screw actuators combine a hybrid step motor, ball screw, drive, and motion controller in a compact package for controlled linear motion. In the TSM Series, the ball screw is integrated directly with the motor shaft while the ball nut is mounted externally. As the motor rotates the screw, the external nut travels linearly along the screw to move the connected load. With the drive electronics and controller built into the motor body, the actuator requires only DC power and a command connection, eliminating a separate drive, reducing panel space, and simplifying motor cabling.
The TSM Series combines the high mechanical efficiency of a ball screw with closed-loop step-servo control for high thrust, smooth motion, and repeatable positioning. Actuators support step-and-direction and CW/CCW pulse commands, stored Q programs for standalone operation, and RS-485 communication using Modbus/RTU. Available control and I/O features vary by motor frame size, allowing the actuator and control configuration to be matched to the application.
Integrated step-servo ball screw actuators are available in NEMA 08, 11, 17, and 23 frame sizes with nominal ball screw diameters from 4mm to 12mm. Stock configurations include 4mm, 6mm, 8mm, and 10mm screw diameters with selected lead options and load capacities for applications ranging from compact positioning systems to higher-thrust linear motion. Input voltage, communication, and I/O capabilities vary by frame size. Ball screws can be ordered unmachined or with standard end machining for integration with bearing supports and other machine components.
