NEMA34 4Nm 572ozin 2phase closed loop easyservo motor with hybrid drive kit HBS86H+86HSM45-E1 leadshine 

it's updating version of HBS86H+86HBM40-1000

Descriptions

The HBS seriesoffers an alternative for applications requiring high performance and highreliability when the servo was the only choice, while it remainscost-effective. The system includes a 2-phase stepper motor combined with afully digital, high performance drive and an internal encoder which is used toclose the position, velocity and current loops in real time, just like servosystems. It combines the best of servo and stepper motor technologies, anddelivers unique capabilities and enhancements over both, while at a fraction ofthe cost of a servo system.

Applications

The HBS seriesoffers an alternative for applications requiring high performance and highreliability when the servo was the only choice, while it remainscost-effective. Its great feature of fast response and no hunting make it idealfor applications such as bonding and vision systems in which rapid motions witha short distance are required and hunting would be a problem. And it is idealfor applications where the equipment uses a belt-drive mechanism or otherwisehas low rigidity and you don't want it to vibrate when stopping.
