Johnson Electric recently introduced the Saia ULE Series Linear Stepper Motors. Available in unipolar or bipolar configurations, these motors provide constant positioning force to 400 N over full travel lengths to 300 mm in ambient temperatures ranging from -15 to +60 degrees C.  Their compact 55 x 55 mm design envelope and NEMA 23 mounting flange enables the ULE series to be mounted in space-restricted applications with great flexibility. The small size and advanced performance of the ULE series stepper motors make them well suited for use in applications such as valve control, positioning and adjustment systems, and control systems for the automation industry. The design flexibility easily accommodates customized design requirements.
