Power small machinery in spaces where other motors won’t fit. Motors are rated for continuous duty. You can wire for clockwise or counterclockwise shaft rotation; instructions are included.
Use a motor speed control (not included) to adjust motor speed. Use an AC to DC transformer (not included) to convert AC power to DC power.
Round-face motors have a solid shaft (no keyway).
Square-face motors have a D-profile shaft.

DC Servomotors
Often used for small automation applications, such as pick-and-place machines, these servomotors deliver lots of power in a small package. With accurate positioning and fine motor control, they create rotary motion based on signals from a drive (sold separately). The commands for speed and positioning are the same as those used for stepper motors, so you can upgrade your system without the hassle of reprogramming it. As these servomotors move, their encoder relays the shaft’s distance, direction, and speed back to the drive. The drive increases your system’s efficiency by taking the electrical signal from the encoder and dynamically adapting the motor’s movements, also accounting for inconsistent loads and unexpected forces.
Drives have several control modes that power the motor—step and direction, position, speed, or torque. Use a computer to set motion parameters and calibrate the servomotor to your system. After initial setup, you can use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. A brake resistor protects the drive from regenerated electricity as the motor slows or stops.

Power small machinery in spaces where other gearmotors won’t fit. Gearmotors pair a motor with a speed reducer to lower speed while increasing torque. Wire for clockwise or counterclockwise rotation.
Use a motor speed control (not included) to adjust the motor speed.
To convert AC power to DC power, see AC to DC transformers.
Gearmotors have ball bearings that withstand heavier loads than gearmotors with sleeve bearings for a longer service life.

Electric Positioning Slides with Automated Controls

With an included controller and an integrated stepper motor, these slides are a complete precision motion control system. The stepper motor moves the low-friction ball screw and carriage smoothly at high speeds, similar to an inkjet printer head. To make sure the carriage is in the right place, the built-in encoder sends data to the controller. At ± 0.02 mm, these slides have a repeatability thinner than a single strand of hair, so the carriage hits the same spot every time. They work well in automated assemblies and other processes requiring accurate, repeatable motion.
For the initial setup, program the slides using the free, downloadable software, THK D-STEP. No coding necessary—simply enter the target position, speed, and acceleration for up to 16 different slides. This software also records position, speed, and motor current data, so you can monitor performance, optimize motion, and troubleshoot issues.
After the initial setup, the controller stores and runs sequences of up to 512 unique steps on its own. The controller also communicates with other devices such as PLCs, switches, and sensors. This means it can be integrated into a larger automated system to react to or trigger other processes as the carriage moves.
Travel distance per turn, also known as screw lead, is how far the carriage moves with one rotation of the ball screw.
Dynamic load capacity is the maximum load slides can move. If you increase the speed, the dynamic load capacity decreases. Use a load-speed chart to confirm which slides will work for your application. Click on a part number and select "Product Detail" to view the chart.
