Descriptions
Leadshine’s iST-23xx integrated stepper is a NEMA 23 stepper motor integrated with an advanced DSP stepper drive.
At very compact size and with all components integrated, the iST-23xx can save mounting space, eliminate motor
wiring time, reduce interference, and cut/reduce cable and labor costs. By adopting Leadshine’s latest current
control technology, the drive of the iST-23xx can drive the stepper motor with high precision, smooth movement,
and extra low noise at low speed movement with no obvious resonance area.
Applications
Leadshine’s iST-23xx can be used in various applications such as laser cutters, laser markers, high precision X-Y tables,
labeling machines, CNC router, etc. Its unique features make the iST-23xx an ideal choice for applications that require
both low-speed smoothness and small mounting space.
