Integrated Step-Servo Ball Screw Actuators - TSM Series
Extended lead time. Contact us for details or alternatives.
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.

The TSM Series pairs the high mechanical efficiency of a ball screw with closed-loop step-servo control, delivering high thrust, smooth motion, and repeatable positioning without the tuning burden of a conventional servo system. Each actuator accepts step-and-direction or CW/CCW pulse input and can run as a standalone axis using stored Q programs or be commanded over RS-485 using Modbus/RTU, with up to 32 devices on a single channel. The NEMA 11, 17, and 23 models add A/B differential pulse input and SCL motion commands, and the NEMA 17 and 23 models support RS-485 daisy-chain wiring. Configurable digital I/O supports servo enable, alarm reset, CW/CCW limit, in-position, moving, brake, timing, and tach functions, with the full set of functions available on the NEMA 17 and 23 models and a reduced selection on the NEMA 08 and 11 frames, and built-in protection covers overvoltage, undervoltage, over-temperature, and motor winding short circuit. The series is RoHS compliant, rated for Class B (130°C) insulation, and operates across a temperature range of 0°C to +50°C with a step accuracy of ±5%.
These actuators are available in NEMA 08, 11, 17, and 23 frame sizes with ball screw nominal diameters from 4 mm to 12 mm, with multiple lead options in the NEMA 11, 17, and 23 frames. Input voltage scales with frame size, and the larger frames add analog command input and expanded I/O, with differential A/B/Z encoder output available on the NEMA 23 models. Screws are supplied either unmachined or with standard end machining for direct coupling to bearing supports and driven members.
